ABSTRACT:
A waveform converter circuit for producing an output square waveform, having a unity mark/space ratio, from an input sinusoidal waveform which can have a large peak-to-peak amplitude range and a large d.c. voltage level range. The circuit comprises a differential amplifier which receives the input waveform at the inverting input. The output of the amplifier is applied to a D-type flip-flop. The flip-flop Q-output is fed via a switched-capacitor filter to the inverting input to provide a corrected d.c. voltage level for the input waveform at this input. The flip-flop Q-output is fed via a switched-capacitor filter to the non-inverting input to provide a slicing level at this input. When the output square waveform has a 1 to 1 mark/space ratio, the corrected d.c. voltage level equals the slicing level. Thus, the circuit will respond to an input waveform with a small peak-to-peak amplitude in the presence of an initial large d.c. voltage level of the input waveform.
