I want to design a CMOS bandgap circuit.So I have to use PMOS to form the diode(the diode 3 in the figure).But how can i simulate this diode?Can i use only source node and bulk node to form a diode(just as in figure) and put this diode in my circuit directly?I have done a simulation of this diode in hspice.but i can't get the correct V-I curve.How shall i do to form a diode with CMOS process.
