Abstract:
1. Circuitry comprising: a ramp signal generator to receive an input signal and to generate a trapezoidal signal based on the input signal; a circuit array to receive the trapezoidal signal and to generate control signals based on the trapezoidal signal; first output transistors having gates to receive a first set of the control signals, the first output transistors comprising a first top transistor and a first bottom transistor, the first top transistor having a source connected to a supply potential and a drain connected to an output, the first bottom transistor having a source connected to a reference potential and a drain connected to the output, the first top transistor and the first bottom transistor being gated by the first set of control signals to control a shape of an edge of an output signal at the output; and second output transistors having gates to receive a second set of the control signals, the second output transistors comprising a second top transistor and a second bottom transistor, the second top transistor having a source connected to the supply potential and a drain connected to the output, the second bottom transistor having a source connected to the reference potential and a drain connected to the output, the second top transistor and the second bottom transistor being gated by the second set of control signals to control the shape of the edge of the output signal.
