  • Analogue portable electrooculogram real time Signal processor
    International Journal of Circuit Theory and Applications, 2014
    Co-Authors: Kyle Fricke, Robert Sobot, Anestis Dounavis

    Abstract:

    We present an Analogue Signal-processing circuit suitable for applications in a portable, wearable, non-invasive electrooculogram-based human–computer interface. Behavioural model and preliminary experimental results confirm that the proposed circuit, while operating in real time, correctly detects and decodes Signals generated by the subject’s eye movements. The total power consumption is measured at 145 mW (excluding the RF link) with a 3 V power supply voltage, and the unit size is approximately 5 cm × 3 cm printed circuit board.

  • A current mode Palmo cell for programmable Analogue Signal processing
    2005 IEEE International Symposium on Circuits and Systems, 2005
    Co-Authors: Yaxiong Zhang, A. Hamilton

    Abstract:

    In this paper a new Palmo cell is presented for the first time. Previous Palmo cells have made use of linear voltage mode circuits and log and square root domain current mode circuits. Here a current mode integrator is used to implement the Palmo cell. The advantage of the design presented here is in the ease of implementation compared to other current mode implementations. It also enables the Palmo cell to be operated in continuous time or sampled-data modes for various Signal processing tasks. Circuits operate with a 3.3V power supply with sampling rates of up to 10MHz for sampled-data circuits.

  • Novel Palmo Analogue Signal processing IC design techniques
    IEE Third one-day Colloquium on Analog Signal Processing (Digest No: 1996 236), 1996
    Co-Authors: K. Papathanasiou, A. Hamilton

    Abstract:

    Introduces and analyses a novel technique for implementing programmable Analogue hardware. Novel programmable Palmo circuits have been introduced which have low switching noise, low THD, and may be configured to perform many Signal processing functions. An initial test chip has demonstrated the viability of the approach and aided in understanding the practical application of the technique. This has led to new ideas for the implementation of the Palmo building blocks to reduce THD and improve overall programmability and performance. Such circuits are ideal for field programmable Analogue array (FPAA) cells. The new Palmo circuit blocks have a dedicated 6-bit current DAC and 3-bit programmable capacitor array giving 9 bits of programmability per cell. Cell interconnect to local neighbours or to pads further enhances programmability and high frequency performance. Dedicated static RAM is used to store the cell parameters and interconnect-which may also be dynamically reconfigured. A new improved comparator is under development to reduce harmonic distortion at high frequencies. These circuits are currently being designed and a new chip is to be fabricated in the near future.
