摘要：

An IC for acquisition of 16 electrophysiology signals in mice is described. Each channel includes programmable gains from 10 to 1000, a 7 kHz low-pass 4th-order Butterworth filter and a sample and hold. Simulations predict 14-bit accuracy up to 7 kHz. The integrated noise from 1 Hz to 7 kHz is 1.9 muV/Hz(1/2). The +/-0.3V de input offset of each channel is cancelled with 7-bit DACs controlling the bulk of the first opamp input transistors and 6-bit DACs on the 2(nd) stage. Total power dissipation is 13.5 mW using a 3V supply. Die area is 6 mm(2) in a 0.25mu process.
