摘要:
A circuit has been developed for the measurement of the electrical characteristics of devices sensitive to extrinsic noise and intrinsic power‐supply transients. The circuit comprises two active current sources running in opposition. The current can be ramped smoothly through current excursions of a maximum of ±1 A. Provision is also made for the modulation of the dc current output by an external ac source.
