A Low-Cost Output Response Analyzer Circuit for ADC BIST

In this paper, a low-cost ADC output response analyzer (ORA) circuit for built-in self-test (BIST) application is proposed. The sine-wave histogram testing method and the basic coordinate rotation digital computer (CORDIC) technique are used to design the proposed ADC ORA circuit. The ADC's static and dynamic parameters can both be obtained using the proposed circuit. The basic CORDIC based ADC ORA circuit is designed and synthesized in a 0.18-mum technology to analyze the outputs an 8-bit ADC to verify the designs. It shows a lower area overhead compared with the fast Fourier transform (FFT) based realization.
