Abstract:
An ambient electric field detector comprising: a collection mechanism disposed to generate a current signal in response to the ambient electric field; an input current mirror operatively coupled to the collection mechanism and disposed to amplify and duplicate the current signal to generate a duplicate signal; and an odd number (i) of at least three nonlinear, over-damped, bi-stable elements coupled uni-directionally in a ring such that the ring of elements oscillates, wherein at least one of the elements has a different initial state than the other elements and each element is disposed to receive the duplicate signal.
