Electronics Letters, Volume 56, Issue 2, Page 69-71, January 2020., 2020 A 4:1 multiplexer (MUX) circuit in SiGe BiCMOS technology intended to directly drive a plasmonic Mach–Zehnder modulator for transmitter applications is presented. To achieve the highest data rates at a high output voltage swing, a power MUX concept is applied that maps the high‐speed performance of the final clock signal onto the output data.
