Characterization of the common mode rejection ratio of amorphous silicon balanced photodiode
physica status solidi c, 2010AbstractIn this work we report on the detailed characterization of an amorphous silicon/amorphous silicon carbide balanced photodiode structure suitable for differential photocurrent measurements. The device is a three‐terminal structure constituted by two series‐connected amorphous silicon p‐i‐n photodiodes.

Integrated balun bandpass filter design with an optimal common mode rejection ratio
2011 IEEE 61st Electronic Components and Technology Conference (ECTC), 2011This paper describes a compact transformer-coupled balun bandpass filter design based on integrated passive device technology. Using a planar transformer with high-density fully symmetrical wiring not only greatly reduces the component size but also provides a superior balance at the differential output ports. In addition, applying the tapped feed-line

Common-mode rejection-ratio analysis using the adjoint network
IEEE Transactions on Circuits and Systems, 1974The computational effort involved in differential-amplifier common-mode rejection-ratio (CMRR) calculations may be reduced by using the adjoint network to obtain the network sensitivities required for the CMRR determination.

Analysis of Dynamic Common Mode Rejection Ratio of Balanced Uni-Traveling-Carrier Photodetectors
Asia Communications and Photonics Conference, 2017The parameters affecting both static and dynamic common mode rejection ratio (CMRR) performance of balanced uni-traveling-carrier photodetectors have been investigated. The differences in device sizes and ohmic contact are the key parameters on the CMRR.

A Highly Linear Operational Transconductance Amplifier (OTA) with High Common Mode Rejection Ratio
2010 International Conference on Signal Acquisition and Processing, 2010This paper presents a highly linear Operational Transconductance Amplifier (OTA) that combines two linearization techniques, one with adaptive biasing of differential pairs and second with using of resistive source degeneration. OTA has ±0.9v power supply and consumes 456 µw.

We propose and demonstrate a plasmonic-based GaAs balanced metal-semiconductor-metal photodetector (B-MSM-PD) structure. A dual-beam FIB/SEM is employed for the fabrication of the metal nano-gratings and slits of the B-MSM-PD. A common mode rejection ratio (CMRR) value less than 25 dB at 830nm wavelength, dependent on the applied bias, is measured ...

Improvement of common-mode rejection ratio in symmetrical differential stages with dynamic load
East-West Design & Test Symposium (EWDTS 2013), 2013The dynamic load structure for symmetrical differential stages based on principle of self-compensation of active elements small-signal parameters influence on common-mode rejection ratio (CMR) is proposed. Shown that this load in traditional stage structure allows to decrease influence of active elements transfer conductance on CMR.

A fully differential class AB two-stage op-amp with and without common-mode feedback circuit (CMFB) are proposed. There are 4 schematics to be proposed. The first schematic is CMOS complementary input with class AB output without CMFB circuit. The second schematic is CMOS complementary input with class AB output stage with CMFB circuit. For low voltage
