Transistors Q1 and Q4 compare charging voltages of mvbr timing capacitors C1 and C2 to fixed reference voltage.When a capacitor voltage is greater than reference.its comparator switches its bistablw mvbr to opposite state,so capacitor is discharged by dump transistor.Arrangement makes output frequency essentially independent of temperqture from-25℃ to+75℃.for frequency range of 0.01 to 100,000 cps,-J.D.Long.Novel Differential Amplifier Stabilizes Multivibrator,Electronics,35:24,p53-54
