A high current drive CMOS output stage with a tunable quiescent current limiting circuit.

A CMOS output stage based on a complementary common source with an original quiescent current limiting circuit is presented. The quiescent current can be varied over a wide range by means of a control current with no need to modify the transistor aspect ratios. The output stage has been coupled to a...
