Resistance ratio determines factor by which value of C1 is multiplied when used in simple opamp circuit shown. With values shown, ratio is 1000 and 10-μF capacitor provides effective capacitance of 10,000μF. Q of circuit is limited by effective series resistance, so R1 should be as large as practical. Opamp type is not critical- Signetics Analog Data Manual, Signetics, Sunnyvale, CA, 1977, p 640-641.
