Abstract: A resonant tank includes a first capacitor formed on a semiconductor substrate, a first inductor formed on the semiconductor substrate, a second capacitor formed on the semiconductor substrate, and a second inductor formed on the semiconductor substrate. The first capacitor, the first inductor, the second capacitor, and the second inductor are connected in a ring configuration, with each capacitor connected between a pair of the inductors and with each inductor connected between a pair of the capacitors. An amplifier circuit is coupled to the resonant tank and configured to amplify a signal in the resonant tank.

Abstract: A method for differential buffer phase correction comprises generating a pair of differential signals from a local oscillator, applying one of the signals to a first inverter and the other signal to a second inverter of a buffer through a differential pair of lines, applying a first positive feedback signal to the first inverter through a first feedback capacitor, wherein the first positive feedback signal is generated from an output of the second inverter and applying a second positive feedback signal to the second inverter through a second feedback capacitor, wherein the second positive feedback signal is generated from an output of the first inverter.

Abstract: The disclosure relates to technology for power supply for a voltage controller oscillator (VCO), where the power supply has a closed loop mode and an open loop mode. In closed loop mode, a peak detector circuit determines the amplitude of the output for the VCO, which is compared to a reference value in an automatic gain control loop. An input voltage for the VCO is determined based on a difference between the reference value and the output of the peak detector circuit. The peak detector circuit can be implemented using parasitic bipolar devices in an integrated circuit formed in a CMOS process. While operating in the closed loop mode, a controller monitors the input voltage and, when the input voltage is stabilized, the controller uses this input voltage value determined in open loop mode.
