An adsorbent for desulfurizing cracking gasoline or diesel fuel comprising 1) pillared clay, inorganic oxide binder, an oxide of one or more metals selected from Groups IIB, VB and VIB, and at least one metal accelerant selected from cobalt, nickel, iron and manganese. According to the method, a first active circuitry layer wafer that includes active circuitry is provided, and a first portion of the first active circuitry layer wafer is removed such that a second portion of the first active circuitry layer wafer remains. A plurality of candidate values for the remaining local frequency error are selected within a predetermined frequency range to include any remaining error of the local oscillator frequency.
