A new 6-bit 250 MS/s analog-to-digital converter (ADC) is proposed for low-power low-cost CMOS integrated systems. This design is based on an improved successive approximation ADC with a mixed-mode subtracter that minimizes the overall power consump
In this paper, a gigahertz monolithic frequency synthesizer was realized in a standard 0.25-μm CMOS technology. It consumes 55 mW from a single 2.5- V power supply, and is fully functional over the complete frequency range of the interest. The outpu
