This paper presents architecture and simulation results of the analog part of a multichannel integrated circuit (IC) for optical radiation sensors (visible and infrared light) that can be used in high-speed applications. The complete prototype, called Optical Radiation Readout Circuit (ORRC) is composed of analog front end and moderate-resolution analog-to-digital converter (ADC) included in every...
The paper presents an optimized architecture of cascaded integrator-comb (CIC) digital filter structure. The structure is suitable for implementation in application specific integration circuits (ASICs) or field programmable gate arrays (FPGAs). The main advantages of the architecture are higher working frequency, smaller area size and lower power consumption. Software in C++ language was written...
In this paper we present a measurement system for multichannel recordings of the electrophysiological activity of brain tissue in vivo. The system consists of: penetrating Microelectrode Array (MEA), three versions of a Conditioning Module each equipped with different Application Specific Integrated Circuits (ASIC's), Digitizer and PC Application for recorded data presentation and storage. The MEA...
