In this work we describe the design and engineering of a multi-channel adaptive electrochemical (EC) signal acquisition system both using Field Programmable Gate Array (FPGA) and Field Programmable Analog Array (FPAA). With inheriting the powerful properties from the above devices, it has both automatic gain and reconfigurable feature. The 16 uniform automatic gain control (AGC) modules in this system...
In this work we describes the design and engineering of a floating-point (FP) data-acquisition system for 16-channel electrochemical (EC) measurement. The system has both automatic gain and peak detection feature. The gain is set automatically dependent on the input amplitude so that at least 13-bit conversion resolution is maintained for the EC signal in the wide range from 48nA to 16mA. Peak detectors...
