Title:

HIGH SPEED LOW POWER CONSUMPTION DYNAMIC COMPARER

Document Type and Number:

WIPO Patent Application WO/2017/049989

Kind Code:

A1

Abstract:

A high speed low power consumption dynamic comparer, comprising a latch, an AND gate, a delay unit, and an XNOR gate. The latch has first to third control terminals. Outputs of the latch pass through inverters I1 and I2 respectively to produce a first comparer output signal and a second comparer output signal. The first comparer output signal and the second comparer output signal pass through the XNOR gate to produce an output signal which is taken as an input signal of the AND gate along with a control signal clk1. An output signal of the AND gate controls the gate of the sixth NMOS transistor P10. The clk1 passes through the delay unit to produce its delay signal clk2. The clk2 is input to the third control terminal of the latch. Output signals Dp and Dn of the comparer pass through the XNOR gate (XNOR) to produce an output signal. This output signal passes through the AND gate along with the control signal clk1, thus producing a control signal of the NMOS transistor P10, thereby solving the problem of static power consumption in a traditional structure.
