NOVEL OSCILLATORS USING CURRENT AND VOLTAGE FOLLOWERS

Two novel oscillator circuits with both voltage and current outputs ar e proposed. The two oscillators are related to each other by the adjoi nt network theorem. Each oscillator employs a current follower and a v oltage follower, and has tire advantage of independent control on the frequency of oscillation and the condition of oscillation. A new minim um R,C oscillator with voltage and current outputs is also given. Two new two-resistor two-capacitor current-mode ald voltage merle oscillat ors ar e also included. P Spice simulation results illustrating the pe rformance of the oscillator circuits are included. (C) 1998 The Frankl in Institute. Published by Elsevier Science Ltd.
