Abstract
Neural signal amplifiers include an operational amplifier and a feedback network coupled between an output and an input thereof. The feedback network includes a tunnel field effect transistor (“TFET”) pseudo resistor that exhibits bi-directional conductivity. A drain region of the TFET may be electrically connected to the gate electrode thereof to provide a bi-directional resistor having good symmetry in terms of resistance as a function of voltage polarity.
