To detect neural spike signals, low-power neural signal detection amplifiers must amplify small neural signals of a few hundred Hz frequency while suppressing large a DC offset voltage, a 1/f noise of MOSFETs, and an induced noise of AC power supply. To overcome the problem of unwanted noise at such a low signal level, a low-noise neural signal detection amplifier with low-frequency noise suppression scheme was developed utilizing a new autozeroing technique. A test chip was designed and fabricated with a mixed signal 0.18 mu m CMOS technology. The voltage gain of 36dB at the bandwidth of the neural signal and the gain reduction of 20dB at AC supply noise of 60Hz were obtained. The input equivalent noise and power dissipation were 90nV/root-Hz and 90 mu W at a supply voltage of 1.5V, respectively. |
