Let's Program the Transistors
Resistive divider circuit can alternatively be called as voltage divider circuit. Such a circuit is shown in the following figure: This circuit divides the input voltage Vin depending on the resistance values according to the following formula: Vout = Vin x (R2/(R1 + R2)) Vout is the output voltage, which is nothing but the voltage…
Now we are ready to simulate the layout view off this cell. Let’s open up the schematic view of the cell and copy the SPICE code. Go back to the layout view and paste the SPICE code. Increase the text size of the spice code to 10 by going to its object property (Ctrl+I). The…
Open the layout view of the Resistive_divider cell and then copy/paste (Ctrl+C/Ctrl+V) an additional resistor. Running a DRC (pressing F5) on the above layout results in the following error. By pressing > we see that there is too little space between the N-wells. Move the Nodes apart until the layout passes the DRCs. Of-course the…
