It uses Infineon's publically available libraries, but includes native LTSpice symbols, allowing for easy use and installation. The worst case resis-tance happens when only one of the inputs (A, B, C or D) is equal to 0 while all the rest are equal to 1. The parameters needed to define a MOSFET in LTSpice are as follows: Rg Gate ohmic resistance Rd Drain ohmic resistance (this is NOT the RDSon, but the resistance of the bond wire) Rs Source ohmic resistance. The four-stage PMOS charge pump and its clock wave-forms are shown in Fig. 5 rg=0 nsub=1. The comparator seems to pull up the voltage fine, but when the input is above the threshold it appears to output about 150mv in the simulation. mp 0 1 2 2 PMOS L=0. The multitasking arrow also indicates the direction that the device conducts when the Voltage across the Drain-Source is reversed biased (compared to normal NMOS or PMOS polarities), so the arrow implies current flow from Drain to Source when the drain is positive and source is negative in a PMOS. 在 LTspice 元器件库中的 pmos4 和 nmos4 表示衬底没有和源极相连接。在 LTspice 元器件库 中找到 pmos4,双击它,然后在电路输入界面点击一下,如图 3.
