Dynamic logic circuit including bipolar transistors and field-effect transistors

A dynamic logic circuit containing at least one bipolar transistor and a plurality of field-effect transistors, comprising:

• a bipolar transistor having a collector, a base and an emitter with the collector-emitter current path connected between an output of said dynamic logic circuit and a first potential;
• a precharging means coupled between a second potential and the output of said dynamic logic circuit for precharging said output to a predetermined level according to at least one clock signal which periodically changes its state;
• and
• at least one first field-effect transistor which assumes an on or off state opposite to that of said precharging means in response to the clock signal;
• and
• at least one second field-effect transistor which operates in response to at least one input signal;
• whereby the source-drain current paths of said first and second field-effect transistors are connected in series between the output of said dynamic logic circuit and the base of said bipolar transistor.

A data processing apparatus integrated in at least one semiconductor substrate and containing a dynamic logic circuit;
