Conditioning ΣΔ ADCs for Bluetooth
Kathleen Philips, Arthur H. M. van Roermund · Kluwer Academic Publishers eBooks · 2006
Bluetooth [112] is a short-range wireless communication system targeting operation in the 2.4GHz ISM band. In most countries, the channels occupy the band from 2.402 to 2.480GHz. The channel spacing is 1MHz and GFSK modulation is used. The latter implies that all information is contained in the phase of the signal. The Bluetooth standard targets a moderate data-rate (i.e. 1Mbps for the early standard) for use in portable applications as for example headsets, printers, etc. By consequence, cost and power drain are the main challenges on the IC solution.
