  • Patent number: 10038408
    Abstract: A chopper stabilized amplifier that utilizes a multi-frequency chopping signal to reduce chopping artifacts. By utilizing a multi-frequency chopping signal, the amplifier DC offset and flicker noise are translated to the higher chopping frequencies but are also smeared, or spread out in frequency and consequently lowered in amplitude. This lower amplitude signal allows for less stringent filtering requirements.

  • Patent number: 5736878
    Abstract: A very fast circuit for tracking an input signal and holding the value for digitization comprises a holding capacitor, two charging circuits connected to either side of the capacitor and extending between a constant current generator and a supply voltage. Each charging circuit has an input transistor responsive to an analog input signal and a load including the capacitor, as well as a series switching transistor responsive to a sample signal to permit a tracking mode or forcing a hold mode. The load includes a diode to effect a low resistance during the tracking mode when the capacitor is charging and a very high resistance during the hold mode when the capacitor is discharging.
