Abstract: A circuit includes a sensor configured to receive an input signal and to provide a sensor output signal in response to the received input signal. A plurality of mirror circuits are configured to receive the sensor output signal from the sensor and to generate mirror circuit output signals. The plurality of mirror circuits includes a first mirror circuit and at least a second mirror circuit. The first mirror circuit increases its respective mirror circuit output signal until its saturation value is reached. The second mirror circuit increases its respective mirror output signal if the sensor output signal is above a threshold value and until its saturation value is reached.

Abstract: An isolator device (200) includes a differential transmitter, a differential receiver, and a pair of differential signal lines between the differential transmitter and the differential receiver. The isolator device also comprises isolation circuitry along the pair of differential signal lines, wherein the isolation circuitry includes a transmitter-side capacitor for each differential signal line, a receiver-side capacitor for each differential signal line, and at least one common-mode voltage regulation component.

Abstract: A jitter compensation circuit operates in a first conduction state responsive to a high-to low transition of data and a low-to-high transition of data. The circuit operates in a second conduction state when there is no transition of data. The circuit compensates charge to a voltage supply in the first conduction state, thereby reducing voltage drop caused by transition of data.

Abstract: An offset cancellation circuit and method are provided where successive stages of cascaded amplifiers are operated in a saturated state. Biasing is provided, by a feedback amplifier, connected in a feedback loop for each cascaded amplifier, so as to be responsive, in a non-saturated state, to the input of an associated amplifier stage operating in the saturated state.
