Digital circuits containing gates

Abstract

The present application discloses digital circuits including gate circuits. The digital circuit includes: a gate circuit, which is used to perform a logic operation to generate a logic operation result; and a trigger module, which is connected with the gate circuit, and stores the logic operation result as data of a corresponding logic state, wherein the gate circuit includes: a first A group of transistors and a second group of transistors, a third transistor and a fourth transistor, in the case where the third transistor and the fourth transistor are turned on, the first group of transistors and the second group of transistors are connected to each other via the third transistor and the fourth transistor, When the third transistor and the fourth transistor are turned off, the gate circuit cuts off the DC path between the power supply terminal and the ground terminal to reduce short-circuit loss, and the trigger module multiplexes the third transistor and the fourth transistor to control the gate circuit and trigger The connection between the internal circuits of the module. In this digital circuit, the gate circuit and flip-flop are optimally designed as combination circuit modules to reduce circuit cost.

Description

Technical field [0001] The present invention relates to integrated circuit technology and, more particularly, relates to a digital circuit comprising a gate circuit. Background technique [0002] In the digital part of the integrated circuit, implemented using basic logic gate circuit or a composite logical arithmetic operation using the trigger logic gate circuit operation is stored as a result of one of two logic states corresponding to the data, i.e., 0 or 1. According to different logic operations, can be divided into the gate circuit gates, OR gates, NOT gates, NAND gates, NOR gates, and NOR gates, XOR gates and the like. The logical operation result, for example, gate circuit is a pulse signal, the trigger pulse signal is generated based on the logic state corresponding to a steady state level signal. [0003] Gate circuit includes a series, for example, a PMOS transistor and an NMOS transistor connected between the supply terminal and the ground terminal. In the logic oper...

Problems solved by technology

Since the waveform of the input signal is not an ideal step signal, both the PMOS transistor and the NMOS transistor may be in the on state during the rising and falling of the input signal, thus forming a DC path between the power supply end and the ground end, resulting in a switch Short circuit power dissipation during
