An OFDM receiver having an analog multiplier based I-Q channelizing filter, samples and holds consecutive analog I-Q samples of an I-Q baseband, the I-Q basebands having OFDM sub-channels. By these function switching means KK1 and KK2, moreover, the function switching signals are arbitrarily switched from any of no connection, a supply voltage Vcc and a ground potential Vss. 51%CoO10 to 50ppmCr2O310 to 300ppmCuO0-400ppmthe glass exhibiting a redox factor of less than 0. The circuit arrangement according to the invention is realized preferably in such a manner that it comprises separate transistors for sampling and charge transfer. The floating pattern includes a first portion between the e-fuse gate and the e-fuse active portion and a pair of second portions extended upward along both sidewalls of the e-fuse gate from both edges of the first portion. In some implementations, at least one search comprises a main search followed by a sub-search that filters results from the main search.
