Abstract
A single-VCO fractional-N frequency synthesizer is designed for DVB-T and ISDB-T Digital TV tuners. This frequency synthesizer architecture can cover all the frequency bands for both standards with only one VCO and thus the chip area as well as the power consumption can be greatly reduced. The synthesizer was fabricated in a 0.18 mum CMOS process with a 2.2 V power supply and occupies an area of 1.5 mm2. The loop bandwidth is 300 kHz and the total setting time is smaller than 70 mus.
