Abstract

PURPOSE:To realize an ultrahigh speed counter circuit with very a few number of components and simple circuit configuration by connecting a node between a constant current source and a series connection of resonance tunnel diodes to an input terminal and an output terminal. CONSTITUTION:A common node between the constant current source Is and a series circuit of resonance tunnel diodes RD1-RD4 is connected to the input terminal and the output terminal. In setting the current Is of the constant current source to the middle point of the peak current IP and the notch current IV in the resonance tunnel diodes RD1-RD4, (n+1)-set of stable states are obtained. When one resonance tunnel diode is shifted from the low voltage state into the high voltage state, a voltage VOUT applied across the n-set of resonance tunnel diode array is increased by the shift. Thus, the n-adic counter circuit whose output voltage VOUT is decided in response to >=n-set of input pulse number is obtained.
