Abstract: PROBLEM TO BE SOLVED: To provide a temperature stabilized voltage-controlled oscillator.SOLUTION: An integrated circuit voltage-controlled oscillator (VCO) in a battery-powered device, such as cellular phone, can be configured to tune across a fairly wide frequency range by using a relatively narrow control voltage range. The frequency response of the VCO can be temperature compensated, by applying a temperature variable voltage source to varactors 310a, 310b that form part of a VCO resonant circuit. The reference ends of the varactors can be supplied with a temperature-dependent voltage source 370, 380 that has a temperature dependence that substantially compensates for the varactor temperature dependence. The temperature-dependent voltage source 370, 380 can be a proportional to absolute temperature (PTAT) device. The VCO includes a CMOS oscillator manufactured on the substrate, an LC resonant tank on the substrate and at least a pair of varactors 310a, 310b, 320a, 320b having a common anode connection.

Abstract: PROBLEM TO BE SOLVED: To cancel second-order or third-order nonlinearity of a transistor, without depending on the temperature variation or on the manufacturing process drift.
SOLUTION: Mathematically, nonlinearity can be represented by a sum of multiple components where some components have negative sign. The components are proportional to DC currents of a transistor at bias voltages which differ by small amounts. Each bias transistor generates a DC current representing one of the components. A feedback circuit senses the DC signal and generates the bias voltage of the bias transistor that makes the DC signal zero. One of the bias voltages is applied to a main transistor, and as a result, the selected nonlinearity is cancelled.
