    Abstract: Apparatus and methods for tuning a voltage controlled oscillator (VCO) are provided. In one aspect, a method of auto-tuning in a phase-locked loop includes generating a VCO clock signal using a VCO coupled to a capacitor array, dividing the VCO clock signal to generate a divided clock signal using a prescaler circuit having a selectable division ratio, controlling a value of the selectable division ratio using a first counter and a second counter of a counter module, generating a phase-frequency detector feedback signal based on a division control signal M and the divided clock signal using the counter module, counting a number of cycles of the divided clock signal that occur during a calibration interval using a cycle counter of a digital processing logic circuit, and determining the value of a capacitor array control signal based on the number of cycles counted during the calibration interval.

    Abstract: Disclosed are CMOS-based devices for switching radio frequency (RF) signals and methods for biasing such devices. In certain RF devices such as mobile phones, providing different amplification modes can yield performance advantages. For example, a capability to transmit at low and high power modes typically results in an extended battery life, since the high power mode can be activated only when needed. Switching between such amplification modes can be facilitated by one or more switches formed in an integrated circuit and configured to route RF signal to different amplification paths. In certain embodiments, such RF switches can be formed as CMOS devices, and can be based on triple-well structures. In certain embodiments, an isolated well of such a triple-well structure can be provided with different bias voltages for on and off states of the switch to yield desired performance features during switching of amplification modes.
