Abstract
Embodiments of a circuit for use with an inter-chip connection that has a variable complex impedance (which can be conductive, capacitive or both), a system that includes the circuit, and a communication technique are described. This inter-chip connection may be formed between a microspring or an anisotropic film and a metal connector on or proximate to a surface of a chip. Moreover, the circuit may mitigate signal distortion associated with the variable complex impedance. For example, the circuit may include an internal impedance that is electrically coupled in series with the metal connector, and that has an impedance which dominates the variable complex impedance over a range of operating frequencies. Separately or additionally, the circuit may be adapted to correct for the signal distortion.
