Microelectronics Neural Bridge IC with Voltage Stimulation*
A microelectronics neural bridge IC with voltage stimulation designed in CSMC 0.5^m CMOS process is presented. This IC is expected to be used for bridging animals spinal nerves or peripheral nerves. It is composed of a neural electrical signal detecting circuit, a signal amplifying circuit, a DC offset compensating circuit and a functional electrical stimulation (FES) circuit. Two high performance op-amps are designed in the microelectronics neural bridge IC: a low noise op-amp and a constant-transconductance (constant-gm) railto-rail input/output op-amp. According to the neural signal spectrum, the bandwidth of the IC is designed from 400 Hz to 4 kHz. The chip area is 1050um×850μm. The power consumption is 914μA when the supply voltage is ± 2.5V.
