Jitendra Mohan has proposed a new first order all-pass filter with its application in realizing an oscillator. The fitler consists of one single active device (MO-DXCCII), and (grounded) 1 resistor and 1 capacitor. In this paper, we present a systematic procedure to realize a wider range of functions where the all-pass filter realization is a special case.
