  • High speed high voltage drivers
    Patent number: 10574222
    Abstract: A voltage driver is provided that includes a driver circuit, comprising (i) first positive channel transistor devices (PCTDs) coupled in series between a reference node and an output node; and (ii) first negative channel transistor devices (NCTDs) coupled in series between the output node and an electrical ground node. The voltage driver further includes a speed-up circuit comprising: (i) second NCTDs coupled to the first PCTDs, configured to discharge gate-source capacitances of the first PCTDs; and (ii) second PCTDs coupled to the first NCTDs, configured to discharge gate-source capacitances of the first NCTDs. The voltage driver further includes a gate voltage circuit coupled to the driver circuit that includes third NCTDs and third PCTDs to provide respective first and second gate voltages to each of a subset of the first PCTDs and a subset of the first NCTDs.

  • Cross-point offset adjustment circuit
    Patent number: 10511294
    Abstract: A differential signal offset adjustment circuit may include a first circuit for receiving a first one of a differential input signal and generating a first one of a differential output signal with positive offset based on a differential offset signal. The circuit may further include a second circuit for receiving a second one of a differential input signal and generating a second one of a differential output signal with a negative offset based on the differential offset signal.
