An alternative analog VLSI implementation of the Meddis inner hair cell model

A circuit implementation of a model of the inner hair cell based on the Meddis inner hair cell model is presented. The model and implementation are alternatives of a previously presented exact implementation of the Meddis hair cell model. Models of the IHC are becoming more computationally intensive and require substantial analogue circuits to allow full implementation. The alternative model is more compact, less complex and more biologically plausible. The current mode circuit uses a modified differential pair input stage, translinear multiplier and translinear first order low pass filters to create large time constants with small capacitors.
