20 kHz ASTABLE


Posted on Feb 7, 2014

Single-capacitor circuit is reIiable over wide range of temperatures. voltages. and transistor gains. Frequency varies only by 0. 05% for supply voltage changes between 6 and 12 V. Timing can be changed with R1. R2. and C. Ducy cycle depends on ratio of R3. to R4. and is 50% forvaluesshown. -C. Horwitz, Tolerant Astable Circuits. Wireless World. Feb
