摘要：A frequency oscillator tuning process at the manufacturing stage is replacedwith an adjustment of a resonant circuit in the frequency oscillator during an operation ofthe oscillator. The adjustment utilizes a crystal oscillator, a frequency oscillator such as avoltage-controlled oscillator (VCO), and a trimmer in a phase-locked loop configurationto determine a correction voltage required for an untrimmed VCO to operate at anominally specified frequency by adjusting an input tuning voltage for a resonant circuit.
