  • Publication number: 20250211214
    Abstract: Fast-charge shaping circuits and methods for shaping the output of a fast-charge one-shot circuit so as to more precisely shape a fast-charge pulse to a bypass switch placed in parallel with an LNA bias resistor in order to decrease the response time of the LNA to circuit mode changes while minimizing perturbations. Accordingly, the settling time of the LNA during mode changes is less dependent on bias resistance, thereby enabling a Noise Figure improvement. A first approach staggers the release of a fast-charge pulse or pulses over multiple resistor segments to gradually increase the effective resistance of bias resistors. A second approach applies a diode and RC filter to a fast-charge pulse to shape the pulse to gradually increase the effective resistance of bias resistors. A third approach uses an op-amp and timing circuit to control the fast-charge pulse shape to gradually increase the effective resistance of bias resistors.

  • Publication number: 20240429584
    Abstract: Methods and devices to address antenna termination in absence of power supplies within an electronic circuit including a termination circuit and a switching circuit. The devices include regular NMOS devices that decouple the antenna from the switching circuit in absence of power supplies while the antenna is coupled to a terminating impedance having a desired impedance value through a native NMOS device. The antenna is coupled with the switching circuit via the regular NMOS device during powered conditions while the antenna is decoupled from the terminating impedance.

  • Publication number: 20240178798
    Abstract: Frequency-selective feedback circuits and methods for an amplifier (particularly LNAs) that improve power supply rejection in feedback circuits, reduce non-linearities caused by low-frequency noise coupled to the input of the LNA, and improve settling times of the quiescent bias-point of the LNA. Some embodiments allow multiple modes of operation to allow selection of gain versus linearity characteristics. One aspect of the present invention includes an input matching feedback circuit configured to be coupled between an input terminal of an amplification core and a feedback node in the output signal path of the amplification core, the input matching feedback circuit including a power supply rejection resistor configured to provide a low-impedance path to a reference potential for low-frequency noise.

  • Publication number: 20190232562
    Abstract: Under the inventive process, the customised split insole is made by processing manually collected medical data and arch data along with plantar pressure distribution data and foot type data both of which are collected using a computer enabled Plantar Pressure Measuring Device in a first computer and processing these data in a second computer to generate a Projection Data which is expressed in Shore Hardness Value. Then, ranking of the projection data into a zone wise Ranking Index, determining the elasticity of the material to be used for the said Shore Hardness Value, converting the said shore hardness value into Surface Tessellation Language and transmitting the same to a third computer built into a 3D printing machine which selects a suitable material and its elasticity zone wise as per the Shore Hardness Value and 3D prints the same.
