This paper presents an analogue VLSI circuit which implements three particular receptors of the chemical synapse: AMPA, GABAA and GABAB. The dynamics of postsynaptic receptor is implemented in CMOS current mode circuits. Furthermore with the implementation of chemical sensors in CMOS technology, the possibility of realising complete synapses which model the non-linear electrochemical behaviour of...
While the CMOS analog circuits can be designed with the minimum-gate-length of the fabrication process in the alpha-power law MOSFET model, the length of a MOSFET gate has been chosen to be a larger scale than the minimum-gate-length in the conventional Shockleypsilas square model. In this paper, we describe a 6-b 100 MSPS CMOS current steering digital-to-analog converter (DAC) with the alpha-power...
