Single opamp circuit provides precise duty-cycle control of pulse train over wide dynamic range by choice of values for R1 and R2. Opamp forms gain element of astable MVBR, with pulse and space time intervals determined by feedback elements. Values shown give duty-cycle ratio of 0.001 and period of 1 s. J.
