## Abstract This article presents a CMOS quadrature voltage‐controlled oscillator (QVCO). The LC‐tank QVCO consists of two cross‐coupled __n__MOS divide‐by‐2 injection‐locked frequency divider (ILFDs) with a tail transistor, which serves the role of frequency doubler. The output of the tail transis
## Abstract In this article, a 40‐GHz subharmonic Gilbert down‐conversion mixer with an accurate quadrature local oscillator (LO) input is demonstrated using a standard 0.13‐μm CMOS technology. The quadrature‐output frequency divider is realized by injection‐locked oscillators and is used at the LO
