Abstract
Embodiments of the present invention include an electronic circuit for performing current sensing. In one embodiment, the present invention includes a first switching transistor and a second switching transistor both coupled to receive a first switching current and a switching signal, and one or more transistors coupled in a first series. A first terminal of an initial transistor in the first series is coupled to a second terminal of the second switching transistor. A second terminal of a last transistor in the first series is coupled to a reference voltage. The first switching current is coupled to a second node between the second terminal of the second switching transistor and the first terminal of the initial transistor in the first series. In this manner, the circuit produces a switching voltage corresponding to said first switching current.
