Abstract
So as to be directly connected to the predefined logic circuit PLC to form a baseband modem, the analog circuit BBAC is monolithically integrated in accordance with the CMOS technology, using switched-capacitor filters which are driven by only one clock. The automatic equalizer EGA is likewise designed from switched-capacitor filters, equalization being obtained by variable and symmetrical clipping of the signals. In these conditions the modem can operate automatically in a very wide range of data rates.
