Ordinary resistor as load in a transistor amplifier has a certain short coming…we cant have voltage and current gain simultaneously …..means that if we need large voltage gain R load value should be very large ..and on other hand if we need high output current (Ic) R load value should be low..
In this circuit a current mirror is actings as an active load in place of R load …I wonder how this current mirror able to give voltage as well as current gain at same time??
