Abstract :
A new ICO/VCO circuit is proposed, having the ability to work from a lower voltage supply at higher speed than the existing ones. On 0.8 /spl mu/m BiCMOS (14 GHz NPN) an amplitude of 0.4 V at 1 GHz and consumption of only 5.6 mW from 2.2 V power supply is achieved. The control ability is 750 MHz/mA. The circuit has very low phase noise and it is suitable for modern PLLs.
