It was an Analog Design innovation Contest at Si-Vision

design of a high precision low voltage bandgap reference circuit on "65nm Tsmc" that could be powered down by a control signal. The circuit was designed using cadence tools in TSMC 65 nm technology and was verified against corners and mismatch variations (Monte Carlo). The circuit delivers a constant Vref = 500 mV and Iref = 10 uA with less than (±3% PVT variation) and less than (±4% mismatch variations) and a PSRR = -50.2676 dB @ DC . The startup time of the circuit is ~ 1.6 us . The circuit was optimized to minimize the power consumption and area.

Designed the fully differential folded cascode to meet required specs (current consumption, DC loop gain, phase margin, differential output swing, closed loop bandwidth, CMIR)

Designed the two stage miller OTA to meet required specs (e.g.: CMIR, static gain error, phase margin, GBW, slew rate, current consumption)

Designed ALU to perform 16 basic signed operations (AND, OR, NOR, Addition, Subtraction, Multiplication, Transfer, NAND, ... etc. ), while minimizing the area and power consumption.
