(TU Delft Electronic Instrumentation) Sebastiano, F. (TU Delft (OLD)Applied Quantum Architectures) Quan, Rui (NXP Semiconductors) van Veldhoven, Robert (NXP Semiconductors) Makinwa, K.A.A. (TU Delft Microelectronics) Department Microelectronics Date 2017 Abstract This paper presents the first dynamic zoom ADC. Intended for audio applications, it achieves 109-dB DR, 106-dB signal-to-noise ratio, and 103-dB SNDR in a 20-kHz bandwidth, while dissipating only 1.12 mW. This translates into the state-of-the-art energy efficiency as expressed by a Schreier FoM of 181.5 dB. It also achieves the state-of-the-art area efficiency, occupying only 0.16 mm2 in the 0.16- μm CMOS. These advances are enabled by the use of concurrent fine and coarse conversions, dynamic error-correction techniques, and a dynamically biased inverter-based operational transconductance amplifier.
