CA3080 oparnp is connected as current-controlled integrator of both polarities for use in current-controlled triangle oscillator.Frequency depends on values of C and opamp bias current and can be anywhere in audio range of 20 Hz to 20 kHz. Square-wave output is obtained by using LM301A opamp as Schmitt trigger.-S. Franco, Current-Controlled Triangular/Square-Wave Generator, EDN Magazine, Sept. 5, 1973, p 91.
