<p>A balanced frequency responsive circuit (9) comprising circuit components formed in a semiconductor chip having first and second on-chip contact terminals (12, 13) which connect to first and second off-chip contact terminals (14, 15), respectively, and a balanced parallel resonator circuit (20) coupled to the contact terminals (12-15). The resonator circuit (20) comprises a capacitance portion (C1', C2', C3') and an inductance portion (L1', L2'). Part (C1') of the capacitance portion is on-chip connected between the first and second on-chip contact terminals (12, 13). Another part of the capacitance portion (C2', C3') and the inductance portion (L1', L2') are off-chip series connected between the first and second off-chip contact terminals (12, 13), such that the contact terminals (12-15) are comprised in a single resonant loop, essentially producing no spurious resonance signals. <IMAGE></p> |
