Abstract / Description

A novel circuit for investigating BJT current source dynamic resistance and capacitance is described and analysed. This circuit is a single-stage differential amplifier driving series-connected diodes, and has the unusual property that its differential gain is equal to the number of load diodes. The circuit is suitable for determining current source dynamic resistance and capacitance at low bias currents, and allows their values to be extracted from common-mode data by curve fitting. Sample dynamic resistance and capacitance results are reported and compared with values obtained from SPICE simulation.
