Bandgap-Based Reference Circuit

An early analog circuit lab in TSMC 0.18 µm CMOS. I built the schematic and ran pre-layout simulations, including a temperature sweep.

Schematic of the reference circuit.
Process
TSMC 0.18 µm CMOS
Completed scope
Schematic, pre-layout simulation, and temperature sweep
Documented result
Approximately 2.54 V output and 25 ppm/°C over approximately −40°C to 100°C
Not completed
Layout, DRC/LVS/PEX, post-layout simulation, and PVT/process corners

The exercise stopped at schematic simulation. Layout, extraction, and post-layout verification were outside the completed scope.
