摘要/Abstract：
A 14-bit 10mW 2MHz BW continuous-time (CT) ΔΣ modulator, implemented in UMC 180nm process, is presented in this paper. High-speed high-resolution low-noise dynamic latch comparator is designed for quantization. A low-latency dynamic element matching (DEM) module is included in consideration of nonlinear mismatching of DAC units. RPI introduces direct feedforward path around the quantizer to compensate for excess loop delay (ELD), which is more efficient in power and area compared to conventional structure. The post-layout simulation achieves a SNDR of 79dB with a FOM of 350fJ/conv-step and occupies 0.1mm2 active area.
