Cathode-follower phase-shift oscillator
01 September 1955
Expressions are given for the frequency and required gain of the Colpitts oscillator with grounded anode, and for standard and cathode follower forms with RLC and RC phase-shifting networks. An experimental Colpitts oscillator for 24.5 kc/s and an RC oscillator for 137 c/s are described. The cathode follower types are very stable with respect to supply voltage variations.
