Charge based switched matrix and method therefor
A reconfigurable, for example with time, network switch matrix coupling switch charge circuits representing multiply and add circuits (MACs) and neurons (MACs with activations) capable of accepting and outputting proportional to charge pulses through crossbars within said network, said crossbars controlled by local controllers and higher level controllers to setup said crossbar communications.
1 . A device to produce an input(s) weighted summer output comprising:
an input charge storage device;
an output charge storage device;
an input charge coupled to the input charge storage device; and
a charge transfer device coupling the input charge storage device and the output charge storage device;
wherein an output proportional to the input charge multiplied by a ratio of a current source of the input charge and a current source of the charge transfer device is produced by the device;
wherein sourcing of charges to the input charge storage device and the output charge storage device is initiated after coupling of the input charge and stopping the sourcing of charges after the input charge storage device returns to an initial charge level.
2 . The device of claim 1 , wherein an output pulse is proportional to a time it takes to return the input charge storage device to the initial charge level.
