Abstract
A novel monolithic VCO using a transconductance architecture and with adjustable operating and centre frequencies is presented. Oscillating frequencies from <1 Hz to >50 MHz were attained with external capacitors. Power dissipation from a 5 V supply was 150 mW driving a 20 pF load. The die size was 400×1500 μm2 and was fabricated using a 2 μm n-well double-metal CMOS process
