The only components in the simple circuit shown are a CA3048 OTA, a feedback resistor (R1), and a timing capacitor (C1). The output frequency is approximately given by: ƒo≈1/(2πR1C1) Timing resistor R1 should be from 1 to 3.9 MΩ .When R1 is of a greater value, the circuit some-Fig, 75-5 times stops oscillating, depending on the specific CA3048 used.
