Abstract
Abstract A ratioless MOSFET inverter for capacitive outputs consists basically of a pair of MOSFET''s with their sources and drains tied together. The clock input is applied to the common drain connection and to the gate of one of the MOSFET''s and the output is connected to the common source connection. In an alternative construction, the MOSFET whose gate is connected to the clock is replaced by a Schottky diode connected between the source and drain terminals of the data input MOSFET. The clock is connected to the drain terminal of the data input MOSFET, and the output is connected to the source of the data input MOSFET.
