Webfrom parasitic bipolar transistors. SCR gate current injection parasitic can occur in p-well or n-well technology. Voltage mode: When the power supply is increased above the nominal value, the SCR formed from parasitic bipolar transistors can be triggered. 5 SCR d e Current or V DD SCR V Anode VDD < V Anode WebSince in order to prevent the parasitic switch-on the ratio U GS/U DS has to be as low as possible, the ratio U DS/U GS has to be as high as possible and therefore the ratio C GS/C GD has to as high as possible, as well. Thus, it can be recommended that: In order to have a low sensitivity to parasitic turn-on, a CGS/CGD ratio has to be as high ...

We present here the … Webparasitic npn transistor due to manufacturing improvements to reduce the resistance between the base and emitter regions. It must be mentioned also that the parasitic bipolar transistor plays another important role. Its base – collector junction is the famous body diode of the MOSFET.
All CMOS ICs have latch-up paths, but there are several design techniques that reduce susceptibility to latch-up. In CMOS technology, there are a number of intrinsic bipolar junction transistors. In CMOS processes, these transistors can create problems when the combination of n-well/p-well and substrate results in the formation of parasitic … WebDec 24, 2014 · We propose a new method to extract the gain of the parasitic bipolar transistor in ultrathin fully-depleted silicon-on-insulator MOSFETs.
