A simple method for designing instrumentation fully-differential (FD) circuits based on standard single-ended (SE) operational amplifiers (OAs) is presented. It departs from a SE prototype that verifies the desired differential-mode transfer function, thereby leading to FD versions of the circuit. These circuits have a high common mode rejection ratio (CMRR), independent of component imbalances...

This paper describes the development of a very low-power pre-amplifier intended for use in pasteless-electrode recording of the human electrocardiogram. The expected input signal range is 100μV 10mV from a lead II electrode configuration. The amplifier provides a gain of 42dB in a 3dB bandwidth of 0.05Hz 2kHz with an input impedance of 280MΩ and a CMRR of greater than 80dB. Its gain and phase c...
