Modern microelectronics technologies play important roles in body sensor networks (BSN). In this paper a field programmable analogue ASIC working on the discrete-time mode for biomedical signal filtering was presented. The ASIC we have developed incorporates a switched-capacitor based analogue module, a current source, a voltage source, an oscillator, and a double-phase non-overlapping clock source offering different clock rates. By alternating the circuit topologies and the clock frequencies for the on-chip switched-capacitors the ASIC could be dynamically configured as a high-pass filter or a low-pass filter with adjustable cut-off frequencies and pass-band gains. The ASIC was fabricated using the SMIC 0.18 um CMOS technology with a die size of 1.0 mm ×1.2 mm and the power consumption of approximately 1.1 mW. The ASIC was fully tested and the results indicated that the ASIC performed as desired. In the future an autonomous field programmable analogue array ASIC will be developed towards intelligent processing-on-node BSNs.
