Description
We present a programmable ultra low DC current source (ULCS), developed at TUBITAK UME, from 1 fA up to 100 pA with 100 aA resolution. The principle of the device is based on applying a ramp voltage on standard capacitors with values between 1 pF and 1000 pF. The standard capacitors are kept in a temperature controlled box. The device is fully automated with computer control and can be used to generate any currents with 100 aA resolution in its range.
