Abstract
A centre-tapped spiral inductor is proposed for use in fully balanced monolithic bandpass filters. The design consumes only 63% of the area required by two traditional spirals and delivers a common-mode rejecti on ratio approaching 40dB. Moreover, the self-resonance frequency is t wice that of a traditional grounded spiral of the same inductance valu e, enabling higher reactances and Q-values to be achieved.
