    the bandgap reference problem

    hello,RobG the Vref vs temp for both circuit are parabola curvatures,does that mean the Vbe terms are properly banlenced?

    the bandgap reference problem

    hello RobG thank you for your replying,and thank you for reminding me of making a copy of the model file. i dont quite understand your second point "I was asking if the extra 13 mV was coming from a PTAT (proportional to absolute temperature) voltage being added to the output by not...

    cdl exporting problem

    hello ,everyone some errors occured when i exported cdl with icfb,it said: *error* eval: unbound variable - aucdlprintinhconnattributes *error* error detected in netlisting, netlist bypass flag set. *error* could not find netlist procedure: 'viscdlsubcktcall could anyone help me with this...

    SCR layouting style probelm

    hello ,everyone i am layouting a SCR for ESD protection,but i am not sure about the location of P+ and N+ as shown below.in Fig1,inside the N well ,P+ is on the left,but in Fig2,inside the N well,P+ is on the right. i wonder if the scr can be triggered if P+ is on the right since it is...

    the bandgap reference problem

    1 ,yes,the "flat spot" is at almost the same temperature(25 and 30 degree) for both transistors,the delta V is the voltage difference between the top and the bottom of the curvature. 2," are you adding a linear temp co to the circuit?" sorry,can i beg your pardon ? ---------- Post added at...

    the bandgap reference problem

    hello,everyone i am so sorry for replying so late and thank you for your replyings the image below is my circuit ,and some more details are these: both A and B bipolar transistor are vertical (N+/P-base/HVN-well);the doping desity of p- base maybe different( for the resistance of Pbase...

    the bandgap reference problem

    dear all i am designing a bandgap reference circuit using the classical topology,and there are two kind of bipolar transistor(A and B) provided.i get different Vref vs temp curve by using different bipolar transistor,they are both parabola ,but the voltage difference between the top point...
