    • A wideband Voltage Controlled Oscillator (VCO) uses a resonant circuit tunable over a wide range of resonant frequencies. The resonant circuit includes voltage variable elements such that the resonant frequency, and thus the frequency of oscillation, may be electronically tuned. The voltage variable elements are arranged such that multiple control voltages determine the resonant frequency. A first control voltage is applied to a first set of tuning elements and operates as a coarse control of the resonant frequency. A second control voltage is applied to a second set of tuning elements and operates as a fine control of the resonant frequency. Using multiple control voltages on multiple elements allows for a wideband VCO while maintaining a low VCO gain.

    • A self-aligning resonator filter, a self-aligning coupled resonator filter circuit (200), and a television tuner circuit incorporating the filter and the circuit are disclosed herein. The self-aligning resonator filter leverages the local oscillator (208) of the tuner circuit and can be realized with a significant reduction in the amount of off-chip components. The self-aligning resonator filter is configured to align its tunable resonator (206) to resonate at a desired frequency in response to a phase difference measured across a resistance element during a tuning mode, and the resistance element (216) is switched out of the self-aligning resonator filter during a run mode.

The television tuner circuit can be manufactured at relatively low cost while retaining high performance and the ability to be dynamically aligned while in use.
