Abstract :
A compact, versatile and very high speed approach for waveform generation is introduced. It generates triangle and square waveforms. The VCO has a very wide range of oscillating frequencies (from fractions of Hz to 100 MHz in 0.5 mum CMOS technology). The amplitude of the oscillations can be very precisely controlled. It can be used in frequency, amplitude, and pulse width modulation applications as well as in accurate piecewise linear waveform synthesis.
