Abstract
This paper presents the analysis of two low-power noise-efficient multichannel amplifier topologies, the current-reuse and the split-voltage amplifier, using lateral BJT input transistors. The calculated noise, noise-efficiency factor (NEF), and power consumption is compared with simulation results in a 350nm CMOS technology. The designed current-reuse amplifier has a NEF of 3.19 with an input referred noise floor of 8.3 nV/√Hz and the split-voltage amplifier has a NEF of 2.2 and a noise floor of 5.7 nV/√Hz.
