Abstract
A charge mode operation circuit dedicated to detect the correlation between analog input signal and digital code, and for realizing by 'RAKE method' the path diversity reception from the correlation data obtained using the same. The circuit utilizes an analog shift register using at least one charge transfer device for transferring a charge signal packet, a plurality of charge signal generation units, arranged along the analog shift register and provided, respectively, with substantially uniform voltage charge conversion characteristic controlled by a common input sign; and a routing mechanism for selectively transferring output charge packets generated by the plurality of charge signal generation units in given directions according to digital bit signal provided separately.
