  • Read circuit for POSFET type tactile sensor devices
    Patent number: 9719870
    Abstract: A read circuit of an electrical signal produced by a POSFET device comprising a transconductance amplifier connected at an inverting input thereof to the output of the POSFET device; and at least one neuron connected at the output to the transconductance amplifier. The transconductance amplifier is adapted to: receive a signal coming from the POSFET device representative of a force or pressure exerted on the POSFET device, and produce at the output at least one current signal representative of the force or the pressure. The at least one neuron is adapted to receive said at least one current signal and to produce at least one output signal, said at least one output signal being a pulse train having a frequency proportional to said at least one current signal produced by the transconductance amplifier.
