VARIABLE_SLOPE_RAMP_GENERATOR

Published:2009/7/23 22:58:00 Author:Jessie | From:SeekIC

Slope is determined by rate at which C1 is charged by constant-current generator Q1-R4 through Q2. Peak of ramp is determined by R19. Circuit will synchronize over 3:1 frequency range centered on 70 kc.-D. J. Grover, Capacitor Charging Controls Variable Ramp Generator, Electronics, 39:11, p 91-92.
