Abstract
A rectangular-to-sine wave converter circuit (10) is provided that comprises a flip-flop (12) that provides for a square wave and an inverse square wave circuit with fifty percent duty cycles. Each of the square wave signals is passed through a multi-stage low pass filter. The stages of the low pass filters are separated by buffers (26) and (32). The common mode voltage of the output signals at output nodes (40) and (44) are adjusted with respect to an arbitrary bias voltage V.sub.bias by using bias resistors (42) and (68).
