In a dynamic flip-flop circuit with a data selection function, for example, when data having an H value has been selected using a selection signal S0, a first node N1 is L and a second node N2 of a second dynamic circuit 1B is H, so that an output signal Q has an H level. In this case, when none of a...http://www.google.com/patents/US7541841?utm_source=gb-gplus-sharePatent US7541841 - Semiconductor integrated circuit
