Abstract

The invention discloses a C unit with low voltage, high performance and low power consumption, which comprises a PMOS pull-up unit, an NMOS pull-down unit, a signal drive gate, a weak feedback gate and a ground feedback gate; The phase device is used to save data, the ground feedback gate is used to control the working state of the signal drive gate and the weak feedback gate, when the first signal input terminal and the signal input terminal of the low-voltage high-performance low-power consumption C unit are connected to the input signal, the signal The driving gate and the weak feedback gate either work in a weak working state to reduce the current, or the power consumption is drastically reduced by the ground feedback gate; the advantage is that the dynamic power consumption and leakage power consumption are small, and can be applied in a low-voltage environment. NCSU PTM 45nm CMOS process, power supply voltage 0.5V, when the frequency of the first input signal connected to the first signal input terminal is 100MHz, and the frequency of the second input signal B connected to the second signal input terminal is 50MHz, and weak feedback Compared with the C unit, the dynamic power consumption is reduced by 49.6%, the static power consumption is reduced by 11.1%, and the performance is improved by 34.3%.

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,...
