Which transistor array is essential in construction of a mirror circuit.

Q.  Which transistor array is essential in construction of a mirror circuit where the formation of diode takes place by an adjacent transistor?
- Published on 26 Oct 15

a. CA3081
b. CA3046
c. CA3086
d. CA3083

ANSWER: CA3086
 
CA3086 play a significant role in proper execution or operation of the circuit during the construction of mirror circuit. Here, the diode gets formed with an assistance of transistors placed adjacently. However, this type of transistor array ultimately leads to acquire the thermal stability and the requisite amount of collector current in a current mirror circuit.
Due to simplicity in fabrication and operation, current mirror circuit have wide range of applications in the aspects of differential and operational amplifiers.
