Opis:
We have designed, fabricated in 90 nm technology and tested a prototype ASIC for readout of semiconductor pixel detectors for X-ray imaging applications. The 4mm x 4mm readout IC is working in single photon counting mode and contains a pixel matrix of 1280 readout channels with dimensions of 100 µm × 100 µm each. We present the architecture, the measurement results of this IC and our conclusions. To make this chip more attractive for novel experiments, we need to further increase single pixel functionality and at the same time reduce the pixel area. This leads us to the 3D technology with at least two layers: analogue and digital and additionally the sensor layer. We present the concept of the 3D hybrid pixel chip design with small pixel size and the ability to build a dead-space free large area pixel matrix.

Opis:
This paper presents the design and measurements of 64 channel Application Specific Integrated Circuits (ASIC) for recording signals in neurobiology experiments. The ASIC is designed in 180 nm technology and operates with ± 0.9 V supply voltage. Single readout channel is built of AC coupling circuit at the input and two amplifier stages. In order to reduce the number of output lines, the 64 analogue signals from readout channels are multiplexed to a single output by an analogue multiplexer. The gain of the single channel can be set either to 350 V/V or 700 V/V. The low and the high cut-off frequencies can be tuned in 9 ÷ 90 Hz and in the 1.6 ÷ 24 kHz range respectively. The input referred noise is 7 µV rms in the bandwidth 90 Hz - 1.6 kHz and 9 µ V rms in the bandwidth 9 Hz - 24 kHz. The single channel consumes 200 µW of power and this together with other parameters make the chip suitable for recording neurobiology signals.

Opis:
This paper presents the design and measurements of low-noise multichannel front-end electronics for recording extra-cellular neuronal signals using microelectrode arrays. The integrated circuit contains 64 readout channels and is fabricated in CMOS 180 nm technology. A single readout channel is built of an AC coupling circuit at the input, a low-noise preamplifier, a band-pass filter and a second amplifier. In order to reduce the number of output lines, the 64 analog signals from readout channels are multiplexed to a single output by an analog multiplexer. The chip is optimized for low noise and good matching performance and has the possibility of passband tuning. The low cut-off frequency can be tuned in the 1 Hz - 60 Hz range while the high cut-off frequency can be tuned in the 3.5 kHz - 15 kHz range. For the nominal gain setting at 44 dB and power dissipation per single channel of 220 žW, the equivalent input noise is in the range from 6 žV - 11 žV rms depending on the band-pass filter settings. The chip has good uniformity concerning the spread of its electrical parameters from channel to channel. The spread of the gain calculated as standard deviation to mean value is about 4.4% and the spread of the low cut-off frequency set at 1.6 Hz is only 0.07 Hz. The chip occupies 5×2.3 mm⊃2 of silicon area. To our knowledge, our solution is the first reported multichannel recording system which allows to set in each recording channel the low cut-off frequency within a single Hz with a small spread of this parameter from channel to channel. The first recordings of action potentials from the thalamus of the rat under urethane anesthesia are presented.
