An innovative low phase noise sub-harmonically injection-locked voltage-controlled oscillator (SILVCO) with frequency-locked loop (FLL) self-alignment technique is presented in this paper using 90 nm CMOS process. To overcome the issue of narrow locking range, the control voltage of the SILVCO is adaptively adjusted using the FLL technique to refer to the(More)
This paper describes a K-band 2-element phase-array receiver in 90 nm CMOS process. The receiver consists of two low noise amplifiers (LNAs), two vector modulators, and a down-converter mixer. The vector modulators are designed using a modified reflection-type in- and quadrature-phase modulator for amplitude and phase control. At 66 GHz, the measured(More)
