Title: Monostable circuit
Inventor: WADA TAKESHI
IPC: H03K3/0232
Filed: 1978-03-15
Abstract: PURPOSE: To improve the output signal waveform as well as to increase the response speed for the monostable multivibrator circuit by actuating the signal amplifying transistor in the positive feedback circuit in the nonsaturation state.  
     CONSTITUTION: The collector potential of the signal amplifying transistor used in the feedback circuit is always limited to be higher than the base potential. In other words, the amplifying transistor is controlled to operate at the nonsaturation region. The variation of the signal delivered to the collector of the amplifying transistor receives a delay by the capacity existing at the collector, but the storage of the carrier and the delay dut to lowering of h fe  can be prevented by the nonsaturation action. Furthermore, the release time of the output signal can be accelerated to secure a high resistance to the short repetitive action by changing the signal amplifying transistor from the nonconducting state to the conducting state against the trigger input.
