This project shows the design & comparison of two 4-bit current steering DACs, based on Binary and Segmented architectures at VDD=1.8V supply, using high-swing cascode current mirror structures for the current source arrays.

High-Swing Cascode Bias Circuit (PMOS)

HighSwingCurrentSource

1) Binary DAC:

BinaryDAC

2) Segmented DAC:

SegmentedDAC

Testbench for Monte Carlo Simulations:

7_MonteCarlo_DNL_w

Monte Carlo Results:

delta
The standard deviation of the segmented DAC is smaller than that of the Binary DAC, giving better DNL performance.
