A circuit includes a semiconductor substrate, a first ground terminal, a second ground terminal, a driver circuit, a capacitor, a receiver circuit, and a substrate bias circuit. The driver circuit is on the semiconductor substrate. The driver circuit is coupled to the first ground terminal, and has a first output and a second output. The capacitor has a first terminal coupled to the first output of the driver circuit and a second terminal. The receiver circuit is on the semiconductor substrate. The receiver circuit is coupled to the second ground terminal, and has a first input coupled to the second terminal of the capacitor, and a second input coupled to the second output of the driver circuit. The substrate bias circuit has a first input coupled to the first ground terminal, a second input coupled to the second ground terminal, and an output coupled to the semiconductor substrate.

Level shifter circuit

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.

Jitter compensation in integrated circuit devices

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.
