A wideband integrate, Amplify, and Dump circuit in 0.13um CMOS for Ultra-wideband applications

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 80dB of resolution while allowing a low-to-medium dynamic range AID 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.
