When unused digital inputs are left unconnected they will float, which can cause both unexpected logic behavior and excessive current draw. Several simple approaches for managing these unused inputs can save significant debugging grief.

By adding only a few components, you can turn a temperature- and beta-compensated current sink into a common-emitter (CE) amplifier that maintains a stable biased operating point. This architecture is useful for building stable and device-tolerant BJT Class A amplifiers.
