In the circuit shown as Figure 1-1 (a), AD820 is a high-impedance input voltage / current conversion circuit. In the case of neglecting DC error, AD820's 2pA bias current can make input impedance be megohms magnitude. AD654 is voltage / current conversion circuit with a single supply voltage, whcih could make operating current be about 3mA. During the voltage conversion period, VTl output current I (T) could incent AD654 to control the output frequency f. In the circuit, C1 selects 1nF capacitor.
