Abstract
A transmitter circuit includes a slew rate control circuit, a hysteresis circuit, a logic control circuit, and an amplifier circuit. The slew rate control circuit controls a slew rate of an input signal to generate a first output signal. The hysteresis circuit generates a first control signal according to the first output signal. The logic control circuit generates a second control signal and a third control signal according to the input signal and the first control signal. The amplifier circuit generates a second output signal according to the first output signal, the second output signal, the second control signal, and the third control signal.
