Highly-Stabilized Voltage-Controlled Oscillator

Prior art in voltage-controlled oscillators contains many attempts at providing an accurate nominal frequency (sometimes called the free- running frequency) that is also stable with varying circuit temperature and power supply conditions. While this circuit provided good temperature and power supply stability, the free-running frequency accuracy was inadequate, unless an expensive pontentiometer adjustment was included to calibrate the initial free-running frequency.
