WebBody Effect • Body effect: Source-bulk voltage V SB affects threshold voltage of transistor – Body normally connected to ground for NMOS, Vdd (Vcc) for PMOS – Raising source voltage increases V T of transistor – Implications on circuit design: series stacks of devices V T0 A B If V x > 0, V SB (A) > 0, V T (A) > V TO WebBody effect occurs when body or substrate of transistor is not biased at same level as that of source. (basically formation of PN junction diode in case of NMOS as example).

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. In addition, the circuits are helpful of being stable loop characteristic of the analog feedback. 2粉色WebJan 7, 2015 · Jan 2, 2015. #1. Razvan. 53. 0.

For instance, in the case of a PMOS current source, Figure 12 right, the current flows out of VDD. An NMOS source conducts the current (drains the current) to GND, Figure 12 left.
