Zhang, Mingshuang (author)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...master thesis 2023

Li, Xiaoran (author)This thesis proposes a novel low distortion, on-chip sine-wave generator. A low distortion input is required in many test and measurement setups for analog and mixed-signal systems, where the input signal should have less distortion than that contributed by the device under test (DUT). For conventional oscillators, there is a compromise between...master thesis 2017
