This paper presents a wideband and low phase noise millimeter-wave (mm-wave) voltage-controlled oscillator (VCO) fabricated in 130 nm BiCMOS technology. The output signal can sweep from 29.6 to 35.5 GHz, which corresponds to 18.1% tuning range. The LC-tank of the VCO consists of two coupled inductors and a binary weighted varactor bank. The secondary… (More)

In this paper, a fractional-N phase-locked loop (PLL) with an integrated chirp generation circuit block for frequency-modulated continuous-wave (FMCW) radar systems is reported. The circuit is composed of a push-push voltage controlled oscillator (VCO), a feedback divider including pre-scaler and programmable divider stages, a phase-frequency detector… (More)

An integrated frequency sixtupler in SiGe BiCMOS technology is presented. It is composed of a nonlinear differential amplifier used as a frequency tripler followed by a Gilbert mixer used as a frequency doubler. The 3 dB bandwidth of the circuit is 15GHz in between 222 – 237GHz range with peak output power of −4 dBm for 0dBm input power. The… (More)

This paper describes an integrated frequency multiplier, implemented as a Gilbert cell based frequency doubler in a 130 nm SiGe BiCMOS technology. The circuit demonstrates a 3 dB bandwidth of 97–134GHz with peak output power of 1 dBm for 1 dBm input power. The fundamental suppression, measured at the single-ended output, is better than 21 dBc while… (More)

This paper presents a fully integrated millimeter-wave phase-locked loop (PLL) frequency synthesizer fabricated in 130nm BiCMOS technology. It comprises a self-buffered voltage controlled oscillator (VCO) tunable from 29.4 to 33.0 GHz, which corresponds to 11.5% tuning range. The VCO contains a programmable binary weighted varactor bank for phase noise… (More)
