Class D amplifiers (CDA) have been used considerably in audio applications due to their high-efficiency behavior. Compared to standalone analog input CDAs, digital input CDAs are less sensitive to electromagnetic interference (EMI), which is preferred in automotive applications. For digital input CDAs, multi-bit current-steering DACs using tri-level units offer high dynamic range (DR) compared with other types of DAC. The main challenge in designing low total harmonic distortion plus noise (THD+N) and high DR IDAC lies in noise, mismatch, and ISI reduction. In this project, a new ISI resilient dynamic element matching technique is developed for mismatch shaping and ISI reduction in IDAC.
