A G band frequency quadrupler in 55 nm BiCMOS for bist applications
Abstract
In this paper, a frequency quadrupler based on a single ended frequency doubler, a new Marchand Balun with Coupled Slow-wave Coplanar Wave (CS-CPW) lines and a balanced frequency doubler in G band is presented and analyzed for in-situ characterization applications. The experimental results of the frequency quadrupler exhibit at 180 GHz a peak output power of -4.5 dBm associate with a linear conversion gain of -5.5 dB, a frequency bandwidth of 160 to 190 GHz and a DC power consumption of 39 mW. This quadrupler has been fabricated in the 55 nm SiGe BiCMOS technology from STMicroelectronics, the chip area is 1850×780 μm 2 including the pads.
