Circuits that provide a gate boost to address non-linear threshold voltage variation in a CMOS T/H circuit. In embodiments of the invention, a boost capacitor and a feedback amplifier add a signal-dependent threshold voltage to the switch gate over-drive voltage of a switch that controls track and hold circuit sampling. In a modified embodiment, capacitive boost is omitted and the feedback amplifier provides the signal-dependent threshold voltage boost. In another embodiment, a boost capacitor and a diode connected transistor provide the signal-dependent threshold voltage boost. In a modified embodiment, capacitive boost is omitted and the diode connected transistor provides the signal-dependent threshold voltage.
A differential track and hold circuit, each half of the differential track and hold circuit comprising
A method-for making switch on-resistance and channel charge injection linear and independent of the signal in a differential track and hold circuit, wherein each half of the differential track and hold circuit includes a switch for providing a positive or negative version of the input voltage to a sampling capacitor under control of a hold clock, the method comprising steps of:
