Cascode current mirror ( operation, advantages and disadvantages)

cmos analog and mixed signal design jntu hyderabad egate video lectures on cmos analog and mixed signal design disadvantages of simple current mirror necessity of cascode current mirror advantages of cascode current mirror channel length modulation effect is minimized output impedance is increased disadvantage of cascode current mirror minimum voltage across output to maintain output transistors in saturation is large so voltage swing is less gain of cascode current mirror output impedance of cascode current mirror
