    Abstract: A voltage controlled oscillator of a phase locked loop circuit having digitally controlled gain compensation. The digital control circuitry provides binary logic input to the voltage controlled oscillator for a digitally controlled variable resistance circuit, a digitally controlled variable current transconductor circuit, or differential transistor pairs having mirrored circuitry for adjusting the V-I gain. The latter configuration requires the voltage controlled oscillator to incorporate a source-coupled differential pair which is driven by a low pass filter capacitor output voltage, and connected to load transistors; a current source and a current mirror for generating a tail current; individual banks of transistors to mirror the load transistor currents; a digital-to-analog converter with control lines outputted there from, the digital-to-analog converter used to increase the amount of current allowed to flow to the transconductor output, the current being digitally increased and decreased corresponding to an amount of current pulled from the current source, and mirroring the current through at least one transistor mirror circuit.

    Abstract: A DCXO device comprises a crystal resonator (13), and a binary weighted switched capacitor network (14) with a switchable capacitance. A microprocessor (12) is provided for controlling the switched capacitor network to obtain a desired oscillation frequency of the DCXO device. The microprocessor receives (i) an actual oscillation frequency value (16) of the DCXO device and (ii) a desired oscillation frequency value (17), e.g. from a radio base station. The processor is further arranged to calculate a capacitance difference (ΔC 1 ) required for tuning the DCXO device from the actual oscillation frequency value to the desired oscillation frequency value based on static (C 0 ) and motional (C m ) capacitances of the crystal resonator, on the capacitance (C 1 ) of the DCXO device, and on the actual and desired oscillation frequency values, and to switch the switched capacitor network in response to the calculated capacitance difference.
