Low voltage high-performance low-power dissipation C unit

Abstract

The invention discloses a low voltage high-performance low-power dissipation C unit, comprising a PMOS pull-up unit, an NMOS pull-down unit, a signal drive door, a weak feedback door and a ground feedback unit; wherein the signal drive door and the weak feedback door are used for forming an interlocked phase inverter to store data, and the ground feedback door is used for controlling the working states of the signal drive door and the weak feedback door. When a first signal input end and a signal input end of the low voltage high-performance low-power dissipation C unit is accessed with an input signal, the signal drive door and the weak feedback door are worked under a weak working condition to reduce current or are controlled by the ground feedback door so that power dissipation is rapidly reduced. The low voltage high-performance low-power dissipation C unit of the invention has the advantages of low dynamic power consumption and leakage power consumption and can be applied in a low voltage environment. In NCSU PTM 45nm CMOS technology, when the supply voltage is 0.5V, and the frequency of a first input signal accessed by the first signal input end is 100 MHz, and the frequency of a second input signal B accessed by a second signal input end is 50 MHz, the low voltage high-performance low-power dissipation C unit of the invention reduces dynamic power consumption by 49.6 percent and quiescent dissipation by 11.1 percent, and improves performance by 34.3 percent in comparison with a weak feedback C unit.

Description

technical field [0001] The invention relates to a C unit, in particular to a C unit with low voltage, high performance and low power consumption. Background technique [0002] As the integrated circuit process enters the nanometer scale, the chip integration level increases and the clock frequency increases, resulting in a rapid increase in chip dynamic power consumption. The increase of dynamic power consumption has brought many problems, such as: the temperature rise caused by the increase of power consumption will reduce the reliability and stability of the device, and also bring about packaging and heat dissipation problems. Another problem with increased chip power consumption is excessive energy consumption and environmental protection. With the widespread use of electronic equipment, the cost of electricity for electronic equipment will exceed the cost of hardware in the next few years. In addition, with the widespread use of battery-powered devices such as laptops,...
