Abstract: A bias device that modifies the bias of a device based on an input signal to the device. The device may have a fixed bias, and the bias device can be connected in parallel with the fixed bias. The device can be an amplifier, such as a linear amplifier or a class AB amplifier. The bias device can be configured to provide maximum bias during the device's crossover time period.

Abstract: A system and method are provided to regulate resistance in a discontinuous time hot-wire anemometer. The solution removes supply voltage dependency on the mass airflow output signal. Operating the hot-wire anemometer using discontinuous time regulation offers lower system power, but introduces an inverse supply dependent term in the associated transfer function. This effect is removed by multiplying the output signal via a supply dependent signal.

Abstract: The present invention provides a system for limiting energy levels across the output of a driver circuitry segment (100). The system provides an output structure (102) adapted to drive an output load (104). A transconductance component (106) is communicatively coupled to the output structure, and adapted to output a transconductance current that is proportional to the voltage across the output structure. A scaling component (108) is communicatively coupled to the output structure, and adapted to output a scaled current that is proportional, by some scaling factor, to the current through the output structure. A qualifying component (110) is communicatively coupled to the scaling component, and adapted to activate a trigger component (112) when the scaled current passes a first threshold. The trigger component is communicatively coupled to the qualifying component, the transconductance component, and the output structure.

Abstract: The present invention relates generally to a low noise transceiver. The transceiver establishes substantially identical common mode voltages at first and second nodes. A receiver is coupled to the first node for receiving signals. The first and second nodes are connected during a first operating mode to provide a low impedance path for diverting received signals away from the first node and disconnected during a second operating mode to enable the receiver to detect signals received at the first node.

Abstract: The present invention provides an ultra linear, high speed operational amplifier output stage (100). The advantages of the operational amplifier output stage disclosed is significantly higher linearity for the same supply current, or equivalent linearity using a lower supply current. The present invention achieves this using an pre-driver sub-stage (122) having a plurality of translinear loops so that there is no net signal loss to the final sub-stage (123). The output of the disclosed operational amplifier output stage takes the form; &dgr;Io≈&bgr;n*&bgr;p*&dgr;Iin. When used with a localized feedback circuitry, bandwidth is extended.

Abstract: The present invention provides an high beta, high speed operational amplifier output stage (100). The advantages of the operational amplifier output stage over conventional methods disclosed is up to &bgr;2 rather than a single beta. The present invention achieves this using an pre-driver sub-stage (122) having a plurality of translinear loops so that there is no net signal loss to the final sub-stage (123). The output of the disclosed operational amplifier output stage takes the form: &dgr;Io≈&bgr;n*&bgr;p*&dgr;Iin. When used with a localized feedback circuitry, speed performance is increased and bandwidth is extended.

Abstract: The present invention provides technical advantages as a class AB output driver (400) with minimal cross-over distortion. If the differential input to the driver is I+&dgr;I/2 and I−&dgr;I/2, then the current gain is the average of &bgr;n and &bgr;p, more specifically, (&bgr;n−&bgr;p)*I+((&bgr;n+&bgr;p)/2)* &dgr;I. The offset current (&bgr;n−&bgr;p)*I is taken out with a feedback loop.
