A BIST architecture for sigma delta ADC testing based on embedded NOEB Self-Test and CORDIC algorithm

Analog and Mixed-Signal Test

“…Another variant is proposed in [185] and makes use of the COordinate Rotation DIgital Computer (CORDIC) algorithm. The standard approach to measure the static specifications of an ADC is to apply a ramp at the input and obtain the histogram of the number of occurrences of each code at the output.…”
