Abstract
This paper presents design and measurement results of an integrated circuit dedicated to recording and detecting a wide range of biomedical signals. The chip is designed in 180 nm CMOS technology and occupies 1.5 x 1.5 mm(2). It consists of 8 channels responsible for amplification, filtration and detection of biomedical signals. In order to satisfy the requirements of a wide range of neurobiological experiments, the main parameters of a single recording channel, such as voltage gain, frequency band, voltage offset and threshold detection, are controlled independently by on-chip digital registers. The recording part is divided into two separate channels, i.e. an Action Potential (AP) stage and a Local Field Potential (LFP) stage. The voltage gain of the AP and LFP stages can be switched between 55.7/50.3 dB and 50.3/45.1 dB respectively. Corner frequencies of a particular stage can be digitally controlled in a wide range, i.e. the upper cut-off frequency can be changed in the 20 Hz-2 kHz (LFP stage) while the lower cut-off frequency can be tuned at the 120 mHz-3 kHz (LFP and AP stage). The upper cut-off frequency of the AP stage is equal to 6.9 kHz. In addition, the area of the analog part of the recording channel is 0.04 mm(2). A single recording channel is supplied from +/- 0.9 V and consumes about 4.8 mu W of power while the Input Referred Noise is equal to 6.2 mu V resulting in 4.92 of Noise Efficiency Factor (NEF).
