Equivalent-time sampling can improve measurement or sensing systems because it enables a broader frequency band and higher delay resolution for periodic signals with lower sampling rates than a Nyquist receiver. Meanwhile, a digital down-conversion (

This paper proposes a system for measuring unknown resistances for metal oxide MQ gas sensors. The circuit configuration is based on the Anderson current loop interface, which connects directly to an Arduino Mega 2560. We analyze errors arising from

This work presents a small-area 2nd-order continuous-time $\Delta \Sigma $ Modulator (CT $\Delta \Sigma \text{M}$ ) with a single low dropout regulator (LDO) serving as both the power supply for the CT $\Delta \Sigma \text{M}$ and reference voltage b

In this paper a novel ultra-low voltage (ULV) standard-cell-based comparator which provides rail-to-rail input common-mode range (ICMR) is presented. The topology, unlike the others in the literature, uses only 2-inputs NAND gates and is able to oper

The sigma-delta modulator (SDM) is one of the well-established data converter architectures. It is well-known for achieving a high signal-to-noise ratio (SNR). In the SDM, the integrators in the loop filter could suffer from overloading if the signal

Abstract Key parameters of analog‐to‐digital converters (ADCs) are their sampling rate and dynamic range. Power consumption and cost of an ADC are directly proportional to the sampling rate; hence, it is desirable to keep it as low as possible. T

This paper presents a virtual comparative study between the Analog to Digital Conversion (ADC) based Duty Cycle Modulation (DCM) and Sigma-Delta (Ʃ∆) modulation. Indeed, the Ʃ∆ modulation is the most used oversampling technique to carry out ana
