This paper presents a 14-bit 1MS/s extended range incremental A/D converter composed by the cascade of two resettable second-order sigma-delta modulators in 28nm technology. The system is designed for applications in instrumentation electronics for particle physics. Design of the converter is reported, including feasibility study and switched capacitor implementation. Architecture simulation results...
This paper presents a reconfigurable SC audio ΣΔ modulator implemented in a 0.18-mm CMOS technology. The 0.4-mm2 ΣΔ modulator, based on a 2-2 MASH architecture, features several different operating modes in which noise-shaping order, number of output bits, sampling rate, and signal bandwidth can be programmed. The power consumption is always minimized for the selected operating mode. The achieved...
In this paper a large input swing integrated interface circuit for MEMS microphones is presented. It consists of an high impedance input buffer followed by a multi-bit (12-levels) analog second order SigmaDelta modulator and a fully-digital single-bit fourth-order SigmaDelta modulator. The circuit, supplied with 3.3 V, exhibits a current consumption of 215 muA for the analog part and 95 muA for the...
This paper presents a complete interface circuit for capacitive MEMS microphones, consisting of the cascade of a preamplifier, a second-order, multi-bit analog SigmaDelta modulator, and a fourth-order, single-bit digital SigmaDelta modulator. The complete interface circuit features a current consumption of 574 muA from a 3.3-V power supply, achieving a signal-to-noise and distortion ratio (SNDR) of...
