A high‐speed 6‐bit resolution digital‐to‐analogue converter (DAC) for generating four‐level pulse amplitude modulation (PAM4) signals with high waveform quality is designed and fabricated using InP double‐heterojunction bipolar transistor (DHBT) technology. The DAC outputs a clean PAM4 signal at 80 GBd and a sawtooth signal at 80 GS/s.
