A Wideband InP 2:1 Analog Multiplexer with Active Feedback Matching and Switched-Diode Core
Listed in ScienceDB
This work presents a 52-GS/s wideband 2:1 analog multiplexer (AMUX) in a 0.8-um indium phosphide (InP) double-heterojunction bipolar transistor (DHBT) process.
Description
An active feedback input buffer is introduced to compensate for parasitic capacitance, achieving broadband impedance matching and extending the bandwidth (BW) of the input stage. Furthermore, a base-collector-shorted (b-c-shorted) diode topology is utilized as the switching element to enhance sampling rate.
The measured AMUX exhibits a 0.21-fT BW from DC to 34.3 GHz and a mixed-mode input reflection coefficient Sdd11 better than -14.4 dB up to 50 GHz. Large-signal measurements demonstrate clear operation at a sampling rate up to 52 GS/s. The AMUX consumes 659 mW, which is comparatively low among reported designs.
