Design flow:

1-Literature survey of RF vs FIR DACs for suitable implementation in the 28 Ghz sub band

2-System design of the chosen FIR DAC on matlab and simulink.

3-circuit level design of the FIR DAC and verification with system level matlab model.

Design of a high precision low voltage bandgap reference circuit 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 a (±3% PVT variation) and (±4% mismatch variations) and a PSRR = -60 dB @ DC . the startup time of the circuit is < 1us . The circuit was optimized to minimize the power consumption and area.

Designed a 7-bit segmented current steering DAC including the custom digital flipflops and encoder. The designed DAC accomplished an SFDR of 59 dB.

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.
