Adjustable Generator of Edge-Rounded Trapezoidal Waveforms

An approach to design a trapezoidal waveform generator with edge-rounding functionality is presented. The paper describes circuit able to produce edge-rounded trapezoidal waveform. Adjustment of numerous waveform parameters is possible. The signal path inside the circuit is very short. Most of circuitry required for waveform edge-rounding and adjustment is placed outside the signal path and works in DC mode. Keywords—trapezoidal waveform generation, edge-rounding, signal shaping, harmonics reduction.
