Abstract
1,129,886. Transistor monostable circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. 17 Nov., 1965 [12 Dec., 1964], No. 50677/64. Heading H3T. A cross-coupled type transistor monostable circuit has additional regenerative feedback provided by a transformer 11 coupled between output and input of the normally non-conducting transistor 15, the unstable period of the circuit being determined by the time to build up the primary current to saturation. A negative input pulse at 22 renders transistor 16 non- conductive and, by regenerative action, transistor 15 becomes fully conductive. Current builds up in winding 12 until the core saturates whereupon the transformer feedback ceases, the collector potential of 15 begins to rise and the circuit regeneratively restores to its stable state. Diode 23 provides a path for the transformer feedback current and transformer oscillations may be damped by a resistance capacitance circuit connected across a winding.
