    In the differential type monostabel multivibirator using CMOS-XOR/XNOR gates, there is a circuit configuration that the operation of two elements becomes the same in stable sate and the metastable state. And, these circuits has the up mode and down mode operations. Furthermore, the metastable state is not influenced trigger repetition rate, and it is shown by a simple formula expression. © 2011 The Institute of Electrical Engineers of Japan.

    Two simple differential-type monostable multivibrators are proposed and demonstrated in this letter, where the first configuration operated under positive triggering mode utilizes EX-OR gates and the second configuration operated under negative triggering mode employs EX-NOR gates. Both realization methods make use of CMOS logic gates connected with a few passive elements to form as switching circuits. Experimental results show that the ranges of the output pulse widths are from several microseconds to milliseconds. © 2010 The Institute of Electrical Engineers of Japan.

    A novel monostable multivibrator circuit
    This article represents a novel monostable multivibrator circuit in which width and height of the pulse output can be independent electronically adjusted. In addition, the pulse width of output is not restricted to be wider or narrower than that of input pulse as conventionally employed. Namely, there is no restriction on the width of input and output pulse, the circuit's implementation is thus more convenient. The proposed circuit is composed of three OTAs, two resistors and one capacitor, basically constructed a simple pulse generator (Schmitt-trigger circuit). Therewith the compactness of the circuit, It Is thus suitable to be fabricated for integrated circuit. The results of circuit simulation is accordance well with theoretical analysis.
