PN结实际CMOS电路在P-diffusion&N-well,N-diffusion&P-wll间存在P-N节。 反向偏置时,存在漏电流。 在Body Bias时,N-well和P-diffustion来自不同power rail,应先对N-wellPIN上电/下电,再对P-diffustionPIN上电/下电,避免产生正向偏置。 🔗VDD与VCCVCC: C=circuit 表示电路的意思, 即接入电路的电压 VDD...

ESD0524P是瞬态电压抑制器(TVS)二极管阵列,具有IEC标准静电放电(ESD)、快速放电(EFT)和电缆放电事件(CDE)保护功能,从而可保护敏感器件,可用于保护最多四个高速数据线和一个电源线(Vcc)。 ESD0524P属于低电容保护器件ESD系列,它采用一种专有工艺技术,频率高于2GHz时,零信号衰减的数据线路电容为0.3pF。该器件所提供...
When an ESD voltage spike occurs, the sense voltage rises above the switch threshold, switching the output of the first inverter. A string of inverters is driven by the first inverter, with a final inverter driving the gate of the clamp transistor. An extending n-channel transistor drives the...

The core extending over the inner 2 ( 140 pc) is found to rotate in the opposite sense with v_rot^core≈ -1/2 v_rot. VCC 510 (M_B -15.7) is therefore by far the faintest and smallest galaxy with a counter-rotating core known. From the main body rotation and the velocity ...
