## Abstract A __g__~m~‐boosted complementary Colpitts differential voltage‐controlled oscillator (VCO) is proposed and implemented in a 0.18‐μm CMOS 1P6M process.It consists of two single‐ended p‐core Colpitts oscillators via __g__~m~‐enhanced cross‐coupled Colpitts transistors to obtain a differen
## Abstract A new fully integrated, dual‐band CMOS voltage controlled oscillator (VCO) is presented. The VCO is composed of two complementary Colpitts VCOs and is implemented in 0.18‐μm CMOS technology with 2‐V supply voltage. The circuit allows the VCO to operate at two resonant frequencies with a
## Abstract The article presents the design of a linear voltage‐controlled 360° analog phase shifter operating at 2.2 GHz. It is a reflection‐type with a simple and compact structure, using a λ/4‐coupled‐line coupler with the output ports terminated with identical parallel‐tuned varactor‐diode circ
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
