## Abstract A 7โGHz NMOS Armstrong crossโcoupled voltageโcontrolled oscillator (VCO) is designed and implemented in a 0.18 ฮผm CMOS oneโpoly sixโmetal (1P6M) process. The differential VCO uses two singleโended Armstrong oscillators coupled via a pair of crossโcoupled transistors and a pair of varact

A new implementation of the injection locked technique is proposed. The incident signal is directly injected into the common-source connection node of the sub-harmonic oscillator instead of the gate of the tail current source, and a narrowband noise filtering network is inserted into the same node t
An RF low phase noise voltage-controlled oscillator is implemented with micromachined IC-compatible variable capacitors and three-dimensional coil inductor. Unlike conventional on-chip passive devices, the micromachined variable capacitors achieve a high-Q value above 60 at 1 GHz with a 15% tuning r
