Title: Voltage-controlled oscillator cmos circuit
Inventor: WANG HONGMO
IPC: H03B5/12
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a high-quality circuit operable at high frequencies by reducing all capacitance values and making large inductance usable for a prescribed LC value. SOLUTION: A transistor couple 32 is contributed to generate transconductance for canceling or overcompensating peculiar resistance R from an LC tank circuit. An appropriate voltage controlled oscillator(VCO) circuit 40 is provided with two couples of transistors, namely, transistor couple 32 of a (p)-channel device and a transistor couple 38 of an (n)-channel device. The respective couples of transistors are connected at both the terminals of an inductor L, and the transistor couple is operated in a push-pull system. Thus, both the couples are contributed to a transconductance value so that the transconductance value is increased and a low-Q inductor having larger characteristic resistance can be used for operation. Thus, tuning is enabled over wide frequencies, while stable oscillation is provided.
