Patent GB-899868-A (GB)
IPC: H03K5/13
Abstract: 899,868. Transistor pulse-generating circuits. GENERAL DYNAMICS CORPORATION. April 4, 1960, No. 11863/60. Class 40(6). A circuit for generating an adjustableduration output pulse in response to triggering by a short input pulse comprises a capacitor, a bootstrap linear charging circuit and means normally short-circuiting the capacitor to render the charging means ineffective, the application of a triggering pulse disabling the short-circuiting means which is subsequently maintained disabled by the charging current flowing into the capacitor until the voltage across the capacitor reaches a predetermined value determined by a catcher diode connected to an adjustable-voltage point, whereupon the charging current ceases to flow into the capacitor, the short-circuiting means is no longer disabled and the capacitor is rapidly discharged. By differentiating the variable length pulse thus produced an adjustable delay can be effected. In the quiescent state, capacitor 10 is discharged through diode 13, resistor 14 and the emitter-base diode of transistor 11. Upon the application of a negativegoing pulse at terminal 16, transistor 17 is rendered conducting whereupon the voltage at its collector moves positively and the diode 13 is cut off to interrupt the discharge circuit for the capacitor 10. The bootstrap circuit, comprising transistor 20, Zener diode 22 and charging resistor 23, commences charging the capacitor 10, the charging current causing transistor 11 to conduct and hence maintain transistor 17 conducting. The voltage at point 12 consequently increases linearly until it reaches the voltage established by potentiometer 24 whereupon the charging current flows instead through the diode 25 so that transistors 11 and 17 are switched off so removing the reverse bias across the diode 13 and permitting the capacitor 10 to discharge. A variable-length rectangular pulse may be taken from the collector circuit of transistor 11 or a pulse with a variable delay may be taken from the output of differentiating circuit 26. In a modified circuit, Fig. 2 (not shown) the transistor 20 is replaced by two cascaded emitterfollower transistors and the Zener diode by a large-value capacitor. In a further modified form of circuit, Fig. 3, the capacitor 10 is short-circuited during the quiescent state of the circuit through the emitter-collector path of normally conducting transistor 44 and the emitter-base diode of transistor 48. On the application of a negative pulse at point 16, transistor 44 is switched off and the capacitor 10 commences charging to switch transistor 48 on, so maintaining the transistor 44 non- conductive. The capacitor continues charging until diode 42 conducts whereupon transistor 48 is switched off and transistor 44 switched on so discharging the capacitor.
