Abstract
A circuit and method for tracking a local oscillator signal frequency in an RF tuner, for tuning input RF signals. The RF tuner includes a frequency-dependent impedance generator that generates a frequency-dependent impedance at the input by rejecting unwanted input RF signals and shunt feeding back the desired signal to the input. The desired signal frequency is centered at the local oscillator signal frequency. The frequency-dependent impedance generator is used with an amplifier circuit to generate a tracking amplifier, the frequency-dependent amplifier gain of which tracks the local oscillator signal frequency.
