Abstract: In today’s increasingly digitally connected world, the analog-digital converter remains a unique key enabling component. This presentation begins with a brief overview of the advancements of high-efficiency ADCs over the last 50 years. It will highlight research and innovation waves and a critical review of the figure of merit. It will derive current research trends and elaborate on two design examples: firstly, incremental delta-sigma modulators as a candidate for high-resolution Nyquist converters with a continuous-time resistive input, where we derive the theory and the implementation challenges of an intrinsically ADC. Second, a wideband continuous-time delta-sigma ADC for automotive receivers will be introduced which achieves an intrinsic linearity of over 100dB without any on- or offchip calibration by the usage of dual quantization. Design and implementation challenges for such performance are reviewed.
