Abstract
Circuitry is disclosed for controlling the slope of rising and falling edges of a signal. The circuitry includes a ramp signal generator that receives an input signal and that generates a trapezoidal signal based on the input signal, and a circuit array that receives the trapezoidal signal and that generates control signals based on the trapezoidal signal. Output transistors have gates that receive a set of the control signals. The output transistors include a top transistor and a bottom transistor. The top transistor has a source connected to a supply potential and a drain connected to an output. The bottom transistor has a source connected to a reference potential and a drain connected to the output. The top transistor and the bottom transistor are gated by the control signals to control a shape of an edge of an output signal at the output.
