Abstract: Disclosed herein is a voltage gain amplifier for use in an automotive radar receiver chain. The voltage gain amplifier utilizes pole-zero cancelation to yield a desired transfer function without gain peaking at a bandwidth in which attenuation is desired, and utilizes a low pass filter effectively formed by a feedback loop including a high pass filter and a differential amplifier to ensure the desired level of attenuation at the desired bandwidth. In some instances, a chopper may be utilized in the feedback loop prior to the high pass filter, and after the differential amplifier, so as to reduce the bandwidth of the differential amplifier in the feedback loop.

Abstract: A read signal generator generates read signals to control read operations of a memory array. The read signal generator can be selectively controlled to generate an oscillating signal having a period that corresponds to a feature one of the read signals. The oscillating signal is passed to a frequency divider that divides the oscillating signal and provides the divided oscillating signal to an output pad. The frequency of the oscillating signal can be measured at the output pad. The frequency of the oscillating signal, and the duration of the read signal feature can be calculated from the frequency of the oscillating signal. The read signal feature can then be adjusted if needed.

Abstract: A method of wirelessly transmitting power includes: causing a power transmission circuit to transmit, to a master power reception circuit, a portion of power it is capable of transmitting; adjusting operation of a slave power reception unit until a first rectified voltage produced by the master power reception circuit and a second rectified voltage produced by the slave power reception unit are equal; causing the power transmission circuit to transmit additional power to the slave power reception unit, resulting in the first and second rectified voltages being unequal; and adjusting operation of the slave power reception unit until the first and second rectified voltages are again equal. A dummy load is connected to the slave power reception unit prior to causing the power transmission circuit to transmit the additional power, and is disconnected once the first and second rectified voltages are equal.

Abstract: A random access memory is connected to a processing unit through a memory interface. Access to the random access is memory is controlled by a process. The memory interface receives a request for access to the memory issued by the processing unit. In response to the request, the memory interface indicates to the processing unit that the memory is not available to receive another access request during a duration of unavailability. This duration can be differentiated depending on whether the received request is a write or read request. The value of the duration of unavailability associated with a write request and the value of the duration of unavailability associated with a read request are individually programmable independently of each other.

Abstract: An input signal having a logic low level at a first voltage and a logic high level at a second voltage is received by a Schmitt trigger. A voltage generator outputs a reference voltage generated from a third voltage that is higher than the second voltage. A first transistor coupled between the third voltage and a power supply node of the Schmitt trigger is biased by the reference voltage to apply a fourth voltage to the power supply node of the Schmitt trigger that is dependent on the reference voltage. The reference voltage has a value which causes the fourth voltage to be less than or equal to the second voltage. A second transistor coupled between the input signal and the input of the Schmitt trigger circuit is also biased by the reference voltage to control the logic high level voltage of the input signal at the Schmitt trigger.

Abstract: A touch-screen-controller (TSC) performs mutual sensing to acquire touch strength values from a touch matrix formed by capacitively intersecting conductive lines. For each line, the TSC generates an emulated self capacitance value from an associated touch strength value based upon a position of that line compared to a location on the touch matrix adjacent to which a first touch type is expected to occur, and determines presence of the first touch type adjacent to the touch matrix based upon the emulated values. The emulated values for each conductive line may be weighted based upon its closeness to the location where the first touch type is expected to occur. The weighting may be zero if its associated conductive line is outside of the location where the first touch type is expected to occur, and may be one if inside of the location where the first touch type is expected to occur.

The transistor is located on a first doped region forming a PN junction of the diode with a second doped region located under the first region.

This change in voltage is compared to a threshold to detect the ionizing radiation.

Abstract: A control circuit for controlling switching operation of a switching stage of a converter includes a phase detector circuit that generates a pulse-width modulated (PWM) signal in response to a phase comparison of two clock signals. A first clock signal has a frequency determined as a function of a first feedback signal proportional to converter output voltage. A first transconductance amplifier generates a first current indicative of a difference between a reference voltage and the first feedback signal, and a second transconductance amplifier generates a second current indicative of a difference between the reference voltage and a second feedback signal proportional to a derivative of the converter output voltage. A delay line introduces a delay in the first clock signal that is dependent on the first and second currents as well as a compensation current dependent on a selected operational mode of the converter.

Abstract: An input signal arranged in frames is received. The frames include a cyclic redundancy check (CRC) field including a number of bits having bit edges. A timing signal is generated to include adjustable duration waveforms at one of a first duration value and a second duration value. A CRC check determines the occurrence, over the duration, of a number of waveforms of the timing signal having their duration adjusted to one of the first duration value and the second duration value which corresponds to the number of bits. A check signal is produced having a pass/fail value. If pass, the duration of the waveforms in the timing signal is maintained adjusted to the one of the first duration value and the second duration value. If fail, the duration of the waveforms in the timing signal is re-adjusted to the other of the first duration value and the second duration value.
