With a current mirror, the current provided to an active
component controls current to a second component. The
device delivers a copy of the input current as output current.
There is a constant factor between the input and output current,
and this factor is independent of the output load. The simplest
configuration consists of two transistors.
Iin = Iout ( 1 + 2/beta), with beta >> 2,
Iin is equal Iout.
For higher precision, the parameters of the two transistors
need to be properly matched (VBE, beta). Integrating the two
transistors into a single package ensures close thermal coupling
and identical behavior of the two bipolar transistors versus
temperature.

Comparator
Differential amplifier configured as a comparator with push-pull output stage. The levels of two input signals are compared and
the output delivers only two states (works in a non-linear mode).
Below an application example which requires four complex discretes and one bipolar transistor. This circuit can be used for
two-step control, analog-to-digital-converter (ADC), and any limit indicators.
