WebThis paper presents four innovative designs of comparators proposed these years. A latch-type dynamic bias adds a tail capacitor to prevent fully discharging at the pre-amplifier output nodes to reduce energy consumption. The comparator is analysed and then compared with floating inverter amplifier (FIA) type. The pre-amplifier of the FIA type … WebThis article presents a fully dynamic scalable switched-capacitor delta–sigma modulator that achieves a 94.1-dB dynamic range (DR). Power-and- bandwidth scalability by only changing the clock frequency is achieved using a capacitively biased and swing-enhanced floating inverter operational transconductance amplifier (OTA). Fabricated in a 180-nm CMOS …

WebAn improved swing-enhanced floating-inverter amplifier (SEFIA) using the correlated-level-shifting (CLS) technique is presented, simultaneously achieving both high gain and high output swing. The proposed SEFIA uses a reused capacitor to replace the dynamic biasing capacitor and input coupling capacitor. One of the two reservoir capacitors ... WebMar 13, 2024 · This brief proposes a fully dynamic discrete-time (DT) Σ ADC using a correlated level shifting (CLS)-assisted floating inverter amplifier (FIA) with a sampling noise cancellation (SNC) technique. The CLS-assisted FIA improves amplifier gain with a single-stage configuration, which has lower input-referred noise than the cascaded one. … Web2 The Inverting Amplifier The basic operational amplifier circuit is shown in Figure 1. This circuit gives closed-loopgain of R2/R1 when this ratio is small compared with the amplifier open-loopgain and, as the name implies, is an inverting circuit. The input impedance is equal to R1. The closed-loopbandwidth is equal to the unity-gain google commodity codes
