Abstract :
Hardware development of a wideband integrate and dump circuit for a new type of Ultra-wideband (UWB) receiver architecture, called a transform domain receiver, is described. For this receiver architecture to be realized, a wide bandwidth integrate amplify and dump (IAD) circuit element is introduced. The IAD interfaces to one of several mixers in a transform domain receiver and uses four timeperiods: integration, amplification, conversion, and dump to provide signal projection onto a basis function (the filtering operation) with 80 dB of resolution while allowing a low-to-medium dynamic range A/D to perform conversion of basis coefficients. The IAD block design in the IBM8RF process is described as well as configuration and evaluation procedures for the constructed IAD device.
