Electronic circuit for fabricating e.g. NAND gate, has current source connected to common node at emitters of differential pair of transistors to increase speed of discharge of stray capacitor during switching of transistors

The circuit has a differential pair (2) of transistors (3, 4) and a current source (9) connected to a node (15) and a power supply. A current source (10) is connected to a common node (7) at emitters of the differential pair of transistors to increase the speed of discharge of a stray capacitor (8) during switching of transistors. The capacitor is connected between the node and ground. An independent claim is also included for a logic gate comprising an electronic circuit. Circuit électronique 1 comprenant au moins une paire différentielle 2 de transistors 3, 4, un autre transistor, une source de courant 9, et une autre source de courant 10 reliée au noeud commun 7 aux émetteurs des transistors de ladite paire 2 pour accélérer la décharge de capacités parasites 8 lors d'une commutation.
