Balanced integrated semiconductor device operating with a parallel resonator circuit

摘要

A balanced frequency responsive circuit comprising circuit components formed in a semiconductor chip having first and second on-chip contact terminals which connect to first and second off-chip contact terminals, respectively, and a balanced parallel resonator circuit coupled to the contact terminals. The resonator circuit comprises a capacitance portion and an inductance portion. Part of the capacitance portion is on-chip connected between the first and second on-chip contact terminals. Another part of the capacitance portion and the inductance portion are off-chip series connected between the first and second off-chip contact terminals such that the contact terminals are comprised in a single resonant loop, essentially producing no spurious resonance signals.
