Abstract

PURPOSE:To reduce the power consumption, by connecting two transistors TRs in series as a load of a slave FF of master-slave type FFs and turning on and off each TR by a clock and the output of the slave FF. CONSTITUTION:TRs T1-T6 constitute a logic part of the slave FF, and TRs T11-T15 constitute its load part. When the clock is low, a current is flowed only through level holding TRs T14 and T15 because TRs T1, T10, T4, and T12 are turned off. When the clock is high, a current is supplied through TRs T11 and T5 (or TRs T13 and T2) because they are conductive, and a capacitor is charged or discharged.

In FIG. 3, first consider an initial state in which the output q is at a high level and the output is at a low level. In this case 1-11, the load transistor T1 is on, Tll is off, and Tlm
is on, elm is on) The drive transistor is on, Ts is on, T1 is on, T4 is on, Ts is off, T is off. The load transistor turns off and Q
On the other hand, when the drive transistor is off, the load transistor is on, and the current is only from one level maintenance transistor, so consumption is small. Next, let us consider a case where the data input is reversed and becomes a low level, and Q and Q are reversed at the next black mark. At t-tl, the mask part is already inverted according to the data input, and the node N
, is at a low level, and node N is at a high level. In this state, the transistor Tll is on and the drive transistor Ts is also on, but since the clock is at a low level, the transistor T1 is turned off and no current flows in the path of the transistors T1 and TI. followed by i
=c When the voltage at ts becomes high level, the transistor T1 is turned on.
Since the pTI path is turned on, Q becomes low level and transistor Ts is turned off. As a result, since a high level is input from the path of the transistors T1 and TI to the r-) electrode of T1 and 1711, a large current charges CL and the output is inverted. When the inversion is complete, each transistor is on the image side, T1 is on, TI is on, TI is on, T
I is off, T3 is off) 711 is on, T1 on the Q side
When T4 is on, TS is on, and T.
