WebThus as the body voltage V B drops then depletion charge (Q dep) increases which increases the threshold voltage (V TH). This effect is called as the body effect or back gate effect. When the body bias voltage V SB … Webthe body-bias could be applied to a p-MOSFET only because the single n-well process does not allow forward-body bias to be applied to n-MOSFETs. Figure 7 shows the leakage current reduction by providing a reverse body-bias of 0.4 V to the p-MOSFET of the inverter with n-MOSFET W/L ratio of 2.4/1.6 and p-MOSFET W/L ratio of 4.8/1.6.

WebEffect of Channel‐to‐Body Bias • When a MOS device is biased in the inversion region of operation, a PN junction exists between the channel and the body. Since the inversion layer of a MOSFET is electrically connected to the source, a voltage can be applied to the channel. VG ≥ VTH Webpn Reverse Bias Current (I1) • Reverse-biased pn junction current has two main components – Minority carrier drift near edge of depletion region – Electron-hole pair generation in depletion region of reverse-biased junction – If both n and p regions doped heavily, Zener tunneling may also be present • In MOSFET, additional leakage can ... WebJun 17, 2014 · Published by Fudgy McFarlen on June 17, 2014. The source and body may not be at the same potential. The curve represented as EFi is the Fermi level from the p substrate through the reverse biased source–substrate junction to the source contact.
