Design of Readout Circuit Based on Probe Neural Biosensor
摘要
Abstract
According to the characteristics of neural signal, a low-voltage and high-speed operational transconductance amplifier has been realized as a direct readout circuit. To reduce the size and cost of this chip, the amplifier uses feedforward compensation technique without Miller capacitor. Using capacitors as a closed-loop feedback not only amplifies the neural signal, but also reduces chip power consumption by replacing the feedback resistor. Simulations were carried out with 0.18 m CMOS technology, and the simulation results satisfied the requirements of neural signal.
