A multiplexer circuit that is capable of accessing 32 internal nodes for the continuous-time probing of signal waveforms is proposed. A chip has been fabricated with eight multiplexer instances and used in experiments for monitoring radiation-induced single-event transients in digital circuits. Pulses with a width of less than 100 ps and pulses over 1 V in height were observed for 230-MeV particle hits. Measurements show 8.5 GHz, −3-dB bandwidth, and a 1.92% total harmonic distortion for a 1-V input range, and a 6.58% total harmonic distortion for a 2-V input range. The measured dynamic range is nominally 26.5 dB.
