This paper presents an approach to implement a high-speed binary weighted digital-to-analog converter (DAC). A different current switching mechanism is proposed that improves the dynamic performance of binary weighted DACs. Circuit simulation shows a

A frequency synthesizer combining a relatively large tuning range (4.12-4.72 GHz) with a low noise sensitivity is presented. A stable fine-tuning loop is combined with an unstable coarse-tuning loop in parallel. As a result, a stable phase-locked loo

This paper presents a fully integrated highly sensitive frequency-shift keying (FSK) demodulator functioning at a modulation factor of 0.5%-0.1% and below. A dual-feedback phase-locked loop approach provides both very high sensitivity and sufficientl
