Abstract
An integrated comparator includes an inverter with a first depletion FET and a first enhancement FET, and a series circuit with a second depletion FET and a second enhancement FET. The second depletion and enhancement FETs are connected in series between a first supply voltage terminal and a first input terminal. A node between the second enhancement and depletion FETs is connected to the gate terminal of the first enhancement FET. The transfer characteristic curve of the second enhancement FET is steeper than the transfer characteristic curve of the first enhancement FET. All of the MOSFETs are of the same channel type. The voltage to be compared is connected between the second enhancement FET and ground. The switching point is determined by the transfer characteristics of the two enhancement FETs.
