An analysis and design of a CMOS differential pair and a common source amplifier for shaping a triangular signal into 0-π/4 segments of sine and cosine waveforms are presented. By multiplexing these two shaped outputs, low distortion full sine and cosine signals can be produced at one fourth the fre...
