A proposed MOSFET-C continuous time biquadratic building blocks

A novel family of MOSFET-C continuous-time biquadratic building blocks is introduced. The proposed family realizes all generic transfer functions such as low-pass, high-pass, and bandpass. It achieves a complete MOS nonlinearity cancellation and does not require use of fully balanced op-amps. A high Q-bandpass filter was designed. The circuit was simulated using SPICE. The design was based on design rules for a standard 3.5- mu m CMOS technology.<
