Abstract

In this paper we present the design and implementation of a low power neural amplifer which has two programmable gains in two programmable bandwidths. The bandwidths are programmable between 0.7-300Hz, suitable for measuring local field potentials and 1.95-5.4kHz, suitable for measuring action potentials. The amplifier achieves a maximum gain of 79dB in the higher bandwidth. A chip has been designed and implemented using a 0.5_m technology with 8 neural amplifiers. On average the neural amplifier consumes less than 14_W at 3.3V.
