    Abstract: A circuit for controlling frequency and/or phase response characteristic of a signal amplification system or channel has a serial architecture composed of a plurality of cells and a selector for deriving the signal after any one of the cascaded cells. At least a component of the RC network of each cell is in the form of a plurality of modules of fractionary value connected in series. A short-circuiting switch is associated with each module of fractionary value and the overall effect may be selected by selecting the derivation node of the output signal and a certain configuration of the short-circuiting switches of the RC networks of the various cells. An outstanding flexibility of selection is achieved.

    Abstract: A TTL/CMOS interface circuit having a tripping threshold unaffected by variations in temperature and supply voltage, comprises an input stage (Si), and an output stage (Su) which is an inverter.
    The input stage comprises a pair of inverters (M2,M3 and M5,M6) powered through a current mirror structure (M1,M4). The first of said inverters (M2,M3 and M5,M6) has an input terminal connected to a voltage reference (VREF) with the same value as the TTL switching threshold, and an output terminal connected to a control terminal (A) of the current mirror structure (M1,M4).
    The second inverter (M5,M6) has an input terminal (IN) forming the input terminal of the interface circuit and an output terminal connected to the output stage (Su).
