Current type level jump monitoring unit

Abstract

The invention discloses a current type level jump monitoring unit, which is used for monitoring late data jump in an adaptive voltage frequency adjustment technology, and is characterized by comprising a charging path unit 1, a charging path unit 2, a controllable switch M9, a phase inverter U1 and a high threshold buffer U2. The jump monitoring unit has obvious advantages in response time and minimum working voltage, and can stably work in a low-to-near threshold region, so that the voltage regulation range is expanded to the near threshold region, and the overall power consumption gain is relatively high; in addition, the response time is very short, and the data hopping condition in the clock high level period can be monitored in an extremely short time.

Description

technical field [0001] The invention relates to a current-type level jump monitoring unit applied in the adaptive voltage technology. The circuit can be used in the adaptive voltage adjustment technology to monitor circuit timing errors, so as to issue early warnings for timing violations. and avoid timing errors. The whole circuit is realized by pure digital logic, which belongs to the field of integrated circuit design. Background technique [0002] With the continuous growth of the scale and computing power of integrated circuits, and application scenarios such as the Internet of Things, embedded devices, mobile terminals, supercomputers and data centers, the energy consumption of devices is increasingly demanding. In IoT applications, terminal devices often require a long battery life. Therefore, energy consumption plays a vital role in the survivability and functional integrity of IoT devices. For mobile terminals, higher requirements are put forward for their standby...
