Design of a MEMS-Based Oscillator Using 180nm CMOS Technology
Micro-electro mechanical system (MEMS) based oscillators are revolutionizing the timing industry as a cost effective solution, enhanced with more features, superior performance and better reliability. The design of a sustaining amplifier was triggered primarily to replenish MEMS resonator's high motion losses due to the possibility of their 'system-on-chip' integrated circuit solution. The desi...
متن کاملA Low Phase Noise CMOS Ring Oscillator Using Phase Modulation and Pulse Injection Techniques
This paper presents a novel design of a ring oscillator (RO) producing eight phases output with accurate signal phase adjustment. By using the pulse injection technique, the RO phase noise has been strongly suppressed. In addition, a novel phase control technique is proposed for the implementation of the phase modulation. The proposed RO achieves a phase noise of -131.5 dBc/Hz @1MHz offset and ...
متن کاملREDUCTION OF THE 1/F NOISE INDUCEID PHASE NOISE IN A CMOS RING; OSCILLATOR BY INCREASING THE AMPLITlJDE OF OSCILLATION
Spectrum measurement results of a CMOS ring oscillator are presented that show a 10 dB decrease in l/f noise induced phase noise at a 2 dB increase in carrier power. Simple ring oscillator theory predicts that the l/f noise induced phase noilse is independent of carrier power. It is shown that an increase in the amplitude of oscillation is accompanied by a reduction of the intrinsic l/f noise o...
متن کاملRF CMOS low-phase-noise LC oscillator through memory reduction tail transistor
Based on the understanding of flicker noise generation in “silicon metal-oxide semiconductor field-effect transistors” (MOSFETs), a novel method for improving the phase noise performance of a CMOS LC oscillator is presented. Zhou et al. and Hoogee have suggested that the 1 noise can be reduced through a switched gate, and the flicker noise generated is inversely proportional to the gate switchi...
متن کاملA low phase noise 20 GHz voltage control oscillator using 0.18-μm CMOS technology
A low phase noise, small power dissipation and small sized K-band cascode differential voltage-controlled oscillator (VCO) with capacitive feedback topology using 0.18 μm CMOS technology is described. The VCO operated can be tuned between 19.1 GHz and 20.9 GHz and has low phase noise of -108.67 dBc/Hz at a 1 MHz offset. The output power of the 20.7 GHz is about -21.12 dBm. The Figure of merit (...
