摘要： One embodiment of the present invention provides a system that facilitates reducing the power needed for proximity communication. This system includes an integrated circuit with an array of transmission pads that transmit signals using proximity communication. This array is comprised of a set of macropads, where each given macropad is comprised of a set of micropads that can be configured to transmit a signal. A steering fabric routes signals to and within macropads, such that a subset of the micropads in the array can be configured to transmit the signal to a receiving component. Each macropad receives a limited number of input signals, with the steering fabric routing input signals to the micropads of the macropads. By limiting the number of input signals that are routed to the micropads of the macropads, the steering fabric eliminates redundant steering configurations for the array and reduces the power needed to transmit the signal.

摘要： One embodiment of the present invention provides a system that facilitates proximity communication. This system includes a circuit containing a bootstrap transistor and a pass-gate transistor, where the drain of the bootstrap transistor is coupled to the gate of the pass-gate transistor. Note that a first coupling capacitance exists between the source of the pass-gate transistor and the drain of the bootstrap transistor and a second coupling capacitance exists between the drain of the pass-gate transistor and the drain of the bootstrap transistor. During operation, the gate and the source of the bootstrap transistor are coupled to a high voltage, thereby causing an intermediate voltage at the drain of the bootstrap transistor. When the source of the pass-gate transistor transitions to a high voltage, the first coupling capacitance and the second coupling capacitance boost the voltage at the gate of the pass-gate transistor higher than the high voltage, thereby enabling the high voltage at the source of the pass-gate transistor to pass to the drain of the pass-gate transistor.

摘要： One embodiment of the present invention provides a system that facilitates reducing the power needed for proximity communication. This system includes an integrated circuit with an array of transmission pads that transmit a signal using proximity communication. A layer of fill metal is located in proximity to this array of transmission pads, wherein the layer of fill metal is “floating” (e.g., not connected to any signal). Leaving this layer of fill metal floating reduces the parasitic capacitance for the array of transmission pads, which can reduce the amount of power needed to transmit the signal.

摘要： A method for calibrating an offset voltage of an amplifier used to amplify capacitively coupled communication signals is described. During this process, a common voltage is applied to one or more inputs to the amplifier. Next, an output of the amplifier is iteratively, measured, and charge is applied to the one or more inputs until the offset voltage is less than a pre-determined value. Note that applying the charge may involve applying a sequence of one or more charge pulses.
