dc.description.abstract | This paper presents a 4-bit, 2?2 multi-stage noise shaping (MASH) delta-sigma modulator (DSM) fabricated using a 0.18??m complementary metal oxide semiconductor (CMOS) process. The DSM was designed using a cascade-of-integrators with a feedforward (CIFF) structure. The first integrator was designed to reduce the loading effect of the system?s front-end circuit using a switched-resistor integrator instead of the conventional switched-capacitor method. The CIFF structure requires an active adder, which is generally implemented with a high-bandwidth high-swing amplifier. In this paper, the active adder is eliminated and an adder-less integrator is implemented in the MASH DSM. The DSM prototype has an over-sampling ratio (OSR) of 16 and a 160?MHz sampling frequency. The prototype?s measured signal-to-noise ratio (SNR) is 82.4 dB and the signal-to-noise-plus-distortion ratio (SNDR) is 78.1 dB for a signal bandwidth of 5?MHz. The measured total power consumption is 26?mW at a 1.8?V supply voltage, and the chip core size is 0.67 mm(2). The energy required per conversion step is 0.4 pJ/conv. | - |
