Abstract :
A continuous time voltage mode Gm-C biquad and its adjoint current mode version are described, tunable by externally applied current sources and employing FCS (floating current source) circuits as building blocks. The gain of both filters is unity. They operate in the pure mode, in which no resistors are used to interconnect self-contained feedback circuits. Gain accuracy depends accordingly on the loop transmission only
