Abstract :
The paper describes techniques for the experimental construction of switched-current circuits, using discrete bipolar transistors and passive components. The techniques developed are useful as a mean for “breadboard” testing of new structures and examination of effects of nonidealities. The bipolar design can be also used in fully integrated BiCMOS realizations, with some the ideas having also applications in CMOS realizations, leading to wider dynamic range and better linearity
