Abstract

Keskin and Biolek have proposed a current differencing transconductance amplifiers configuration for realizing quadrature oscillator using first-order all-pass filters. This paper exploits their all-pass filter configurations for realizing a wider class of current mode transfer functions. The synthesis procedure is illustrated with examples from first-order and second-order all-pass filters.
