Abstract
This paper describes the design and measurement results of a Gilbert Cell based power detector (PD) for built-in Self-Test (BiST) applications in 5G mm-Wave operating at (24–30 GHz) frequency range. The PD is designed and fabricated in TSMC 0.18um BiCMOS technology. This detector is designed for digitally-assisted calibration for transmitter imperfection such as LO feedthrough and Image Rejection. The proposed differential Gilbert based implementation results in a 58dB common-mode rejection required for LO feedthrough and image rejection calibrations. In the matched frequency range, the simulated input dynamic range is over 48 dB, the detector response is varying by around ±1.25 dB for a given input RF power, as the RF frequency is swept across the operating frequency range. Static power consumption is 16mW from a 3.3 V supply.
