Courses
Getting Started
Game-like introduction to ORDeC
CMOS Integrated Circuits
From transistor curves to a 5-transistor OTA in IHP SG13G2
Layout Tutorial
From rectangles and constraints to a DRC/LVS-clean inverter and differential pair (IHP SG13G2).
Competition
Amplifier Competition
Meet the amplifier specs, then minimize supply current. Lowest current wins.
Examples
Current mirror
NMOS current mirror with DC simulation and device parameter extraction.
Common-source amplifier
IHP SG13G2 amplifier with AC bode plot and transient simulation.
Pseudodifferential VCO
4-phase ring oscillator with
constraint-based layout
using IHP SG13G2.
CMOS 2-input NAND gate
Basic schematic including loops and multiple connection styles.
Differential pair
Diff pair with
constraint-based schematic
(Series/Parallel groups) and DC transfer sweep.
Voltage divider
Resistive divider with DC simulation and SPICE netlist export.
SG13G2 standard cells
Imports the SG13G2 standard cells and runs a simple simulation, DRC and LVS with them.
Ripple-carry adder
4-bit adder from SG13G2 standard cells with
automatic place & route
, DRC, LVS and a counting testbench.
Voltage divider (Python)
Same voltage divider circuit, written in pure Python.
RC curve (Python)
RC low-pass filter with transient step response and AC frequency sweep, written in pure Python.
