Even-Order Harmonics Calibration |
摘要 |
Circuits and methods for a differential circuit involve having one of more pairs of differential transistors with back-gate terminals, where each of the back-gate terminals is biased by a tunable back-gate voltage to compensate for circuit mismatches in the differential circuit and reduce or eliminate even-order harmonics in the output signal. A compensation circuit can be configured to receive data relating to the differential output signal of the differential circuit, and to supply one or more back-gate voltages to the back-gate terminals of the differential transistors to adjust threshold voltages of the differential transistors and suppress even-order harmonics in the differential output signal of the differential circuit.
