Abstract

1330781 Electronic watches HAMILTON WATCH CO 1 Jan 1971 [5 Jan 1970] 151/71 Heading G3T [Also in division H3] A pulse shaper comprises a differentiater 30, 34 coupled to a pair of opposite conductivity MOS transistors 42, 44. The two transistors are connected in series with their drain electrodes coupled to an output FET 64 which drives the energizing coil 74 of a transducer driving the hands of an electronic watch. The input to the pulse shaper is derived from a crystal oscillator via a frequency divider. The resistor 34 may be connected to the positive supply terminal, Fig.3, (not shown).
