ABSTRACT:
A CMOS single phase register includes two pairs of cross coupled CMOS inverters connected together by transistor switches. The first pair of cross-coupled CMOS inverters is connected to a complementary pair of data inputs through a first pair of transistor switches which turn on in response to a first logic level. The complementary outputs of the first pair of cross-coupled CMOS inverters is connected to the inputs of the second pair of cross-coupled CMOS inverters through a second pair of transistor switches which turn on in response to a second logic level. The complementary outputs of the CMOS single phase register of the present invention are the outputs of the second pair of cross-coupled CMOS inverters. The ground connections of the first pair of cross-coupled CMOS inverters is made through a transistor switch which turns on in response to the first logic level. The positive voltage supply connections of the second pair of cross-coupled CMOS inverters is made through a transistor switch which turns on in response to the second logic level. A single clock line is connected to the gates of all of the transistor switches.
