Abstract
Disclosed is a harmonic suppression circuit for tunneling magnetoresistance sensors, which restrains even-order harmonic distortion by means of a fully differential interface circuit topological structure, restrains the charge injection and clock feedthrough effect of transistors by means of a virtual geminate transistor parallel structure and reduces the on resistance by means of a complementary switch structure to effectively restrain harmonic distortion. The harmonic suppression circuit for tunneling magnetoresistance sensors has a high linearity and has a high reading accuracy when used for reading sensing data of tunneling magnetoresistance sensors.
