Amplifier Structure for Neural Signal Recording
نویسندگان
چکیده
An ASIC for recording ENG signals has been developed. The basic blocks for a microelectronic solution including an auto-polarised high pass filter and amplifier with band pass filter can be combined on two different structures for implementing a full system amplifier. The design of and results from more important blocks and full system are presented. The circuit has been designed considering to work with cuff electrodes, and performances such as low power consumption, low noise and low offset, without the use of external components, are important characteristics. A 4 channel implantable recording system can be built just repeating some of the structures here presented.

A Sub-µW Tuneable Switched-Capacitor Amplifier-Filter for Neural Recording Using a Class-C Inverter
A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...
