ABSTRACT:
A low current oscillator/buffer amplifier configuration is disclosed which provides a simple, inexpensive, low power oscillator with reduced harmonic output. Buffer 60 is coupled to the resonant tank circuit 58 of oscillator 50 by means of impedance transform network 70. This technique of tapping directly from the tank provides a buffered output signal having low harmonic content. Furthermore, impedance transform network 70 permits coupling feedback amplifier 52 to buffer amplifier 62 in a totem-pole amplifier stage configuration. This feature provides a significant current savings over conventional oscillator/buffer circuits. The instant invention is particularly well adapted for use as reference frequency oscillators in portable radio applications.
