Design and Optimization of the Off Mode of Low-Power MCU
-
Abstract
In this paper, we optimize the supply control in off-mode and meanwhile, simplify the circuit of the supply control unit, which is the core module under off-mode, by using combinational logic circuit to reduce power dissipation. The post-layout simulation shows that the leakage current of supply control unit under off-mode is only 18.87 pA, and a relatively short mode switching time is also achieved.
