Design of Differential Amplifier Using Current Mirror Load in 90 nm CMOS TechnologyDifferential amplifierUGF (unity gain Frequency)Post-layoutCMRR (Common mode rejection Ratio)In this article, a differential amplifier with a moderate gain of 40.56 dB is achieved. The UGF of 46.985 dB and phase ...
The implemention of smart sensor systems requires besides a digital RFID circuit, also sensors, amplifiers and analog-to-digital interfacing circuits. Those are analog building blocks that have to meet certain specifications. The differential amplifier is probably the most important basic analog building...
We describe a fully differential amplifier for oversampled A/D converter applications. This amplifier employs a single stage telescopic architecture using both N-type and P-type gain-boosting technique with capacitive feedback. This architecture offers extremely high gain, low noise, low power and th...
Designing the differential amplifier by inspection is part of the art in the analog design. Inspecting the circuit and knowing how it works, it really gives you a feeling on what the values of the resistors should be. Looking back at the example I took inMasteringElectronicsDesign.com: Solving...
A new fully differential CMOS operational amplifier (op amp) without extra common-mode feedback (CMFB) circuit is proposed and analyzed. In this op amp, simple inversely connected current-mirror pairs are used as active loads. From the theoretical analysis, it is shown that the common-mode sig...

Differential Amplifiers: Utilizing two devices in a differential mode, with input signals of opposite polarity, effectively places the device capacitance in series, roughly doubling the cutoff frequency (fT). Differential amplifiers can also provide a larger output voltage swing compared to a single dev...
