A CMOS XY-addressable imager is a matrix of photodiodes, each of which is provided with a MOS transistor acting as a switch. This setup is shown schematically in Fig. 5. The basic structure of a unit cell is very similar to the one depicted in Fig. 2, where the photodiode is connecte...
A 3-state embodiment of the CMOS buffer uses parallel coupled PMOS-NMOS devices to switchably couple in the resistance between both output gates when the enable signal is high. Second input PMOS and NMOS devices, connected in parallel across the first input PMOS and NMOS devices, turn on ...
区域2(OFF->ON):当阳极A和阴极K的电压进一步增加,直至PN结J2达到反向击穿电压(Breakdown),则正向导通(Forward Breakover)会瞬间发生,所以此时叫做瞬态(Transient State),器件从OFF切换到ON状态,使得I-V曲线呈现负阻状态,所以叫做Snap-back。而此时的电压为切换电压(Switch Voltage)为Vs。
