Abstract: An array of transistor circuits is fabricated so that each transistor circuit in an array of transistor circuits has a switching threshold determined by intrinsic switching thresholds of at least one sensing transistor in a corresponding transistor circuit. The sensing transistors in a set of transistor circuits of the array can be fabricated to have common physical dimensions even though corresponding intrinsic switching thresholds of the transistor circuits can vary. Switching thresholds of the transistor circuits can vary based on an applied well bias voltage. Alternatively, the switching threshold of each transistor circuit can be set to a common value and a tapped delay line can be coupled to the transistor circuits. Consequently, an A/D converter device can be fabricated by coupling an encoder, and a calibration circuit if necessary, to the output of the array of transistor circuits.

Abstract: A system and method are provided for enabling the use of spatially distributed multichannel wireless access points or base stations. There is enabled a setup which allows frequency reuse whilst still giving many clients around the access points access to the multiple channel capability of each access point. This allows larger overall communication bandwidths to be obtained on average, even within the constraints of frequency reuse.
