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

Bioelectrical impedance in vivo measurements suffer from many potential sources of error due to the patient-instrument interface. The total common-mode rejection ratio (CMRR(T)) was investigated experimentally for three measurement channel circuit versions, including electrode-skin impedance imbalance. The first version was of the 'classical' type. The

This paper attempts an analytical approach to accurately determine common-mode rejection ratio (CMRR) considering the effects of various non-idealities such as the presence of channel length modulation, body effect, finite resistance of the current source, mismatches in transconductances and drain resistances between the two driver MOSFETS of a common ...

IEEE Journal of Solid-State Circuits, 1976
A unified treatment of offset voltage and common-mode rejection ratio (CMRR) of bipolar differential amplifiers using large signal models is presented. The offset voltage expressions for the differential pair and 741 stages are first calculated in terms of transport model parameters. CMRR may then be calculated from these expressions.
