Resumo

In this work the Low Dropout Voltage Regulator (LDO) was designed with gate-all-around nanosheet transistors (GAA-NSH). The simulation model was developed using Verilog-A code and the Look Up Table (LUT) was based on experimental data. The gm/ID of 10.5 V-1 was used for the differential pair in the LDO circuit, resulting in a dropout voltage of 340 mV through the power output transistor. The LDO designed with NSH transistors demonstrated promising results, such as an open-loop gain of 57 dB, a gain-bandwidth product of 52 MHz, and a power rejection rate of approximately -70 dB. (AU)
