چکیده
This paper proposed three reverse voltage protection circuits for the power MOSFETs in low dropout applications. Power devices are vulnerable to instantaneous current overshoot when input is lower than output voltage. Compared with conventional solutions using diode block, structures consume fewer drop during normal operation. The first design suitable applications wide ranges but requires largest die area. other two voltages, and characterized effective area arrangement dead-zone free control, respectively. require 126.2%, 12.25% 43.05% extra of devices,

CMOS Low-Power Threshold Voltage Monitor Circuits and Applications
A threshold voltage (VT0) monitor is a circuit that ideally delivers the estimated VT0 value as a voltage at its output, for a given temperature range, without external biases, parametric setups, curve fitting or any subsequent calculation. It can be used in temperature sensors, voltage and current references, radiation dosimeters and other applications since the MOSFET VT0 dependence on the op...
