This self-oscillating clock driver circuit generates two half-sinusoidal, non-overlapping phases of output intended primarily for driving two-phase MOST circuits in a quick-step push-button dial telephone. A Hartley oscillator, modified to include an amplitude stabilization circuit, drives a pair of transistor output circuits which in turn drive the capacitive loads in a push-pull manner. The clock driver arrangement also functions as a master oscillator in the subscriber handset to provide the push-button tone frequencies. |
