Width of output pulse varies with frequency to keep duty cycle constant at preadjusted value from 25% to 75%, over input trigger range of 100 to 5,000 pps. Q1, Q3, and Q4 form one mvbr, and Q5 is second mvbr. Q2 is voltage-to-current converter.-G. P. Klein, Duty Cycle is Constant at any Trigger Frequency, Electronics, 38:15, p 62-63.
