(2015). High gain, and high CMRR two-stage folded cascode OTA with nested Miller compensation. Journal of Circuits, Systems, and Computers (JCSC), 24. doi:10.1142/S0218126615500577M. Akbari and O. Hashemipour, "High Gain and High CMRR Two-Stage Folded Cascode OTA with Nested Miller ...
In the 2 stage OTA you have 6 devices thaa contribute to noise... In single stage OTA's you will always have more than this. For example, the telescopic OTA will have 8 devices. the number increases for folded cascode or current-mirror type OTAs. Regards Not open for further replies....
8, the comparator of the TS-SS ADC is designed with a two-stage topology consisting of a pre-amplifier and a dynamic latch [3, 17]. The pre-amplifier circuit includes a folded-cascode amplifier. So, half of the input-differential-pair circuit replaces the pixel transistor (MSF) inside ...
Conventional two-stage folded cascode operational transconductance amplifier (FCOTA) with Miller compensation is the most commonly used circuit structure, but its low current efficiency makes it less advantageous in terms of the trade-off. Thus in this paper, the two-stage recycling folded cascode ...
This paper presents design of a two-stage folded cascode amplifier with CMOS Technology. Maximum DC gain is the important required factor for analog and mixed signal circuits.The proposed circuit is designed to achieve more than 100 db and the obtained DC gain is 107.615 db. Phase margin is ...
This paper presents an ultra-low power two-stage class-AB recycling double folded cascode (RDFC) fully differential operational transconductance amplifier (OTA) with high DC gain, unity gain frequency, slew rate, and common-mode rejection ratio (CMRR). Design and simulation of the proposed OTA ...
This paper presents a low-noise two-stage operation amplifier design procedure based on standard CMOS process. Unlike the previous researches that depict the design flow based on some simple circuit topologies for simplicity, this paper adopts the folded cascade input and Class AB output two-stage ...
