WebSep 10, 2024 · That means that the body of the NMOS must be connected to ground. The PMOS has it's own N-well and that N-well can also be made larger and shared between several PMOS. In some cases it can be beneficial to connect the N-well not to Vdd but to a lower voltage. This reduces the body effect which increases the threshold voltage.

Webfound that the effect of the parasitic bipolar on PMOS devices is smaller than that of NMOS. That is, it turns out that the accurate body bias voltage value for rectifying to the defined Vt is outputted from the proposed circuits.
