Title: Waveform generation circuit
Inventor: ARAI KUNIHIRO
IPC: H03K3/356
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and to increase the operating speed of a waveform generation circuit by utilizing the nonlinear current voltage characteristic of a negative differential resistance element. SOLUTION: An input high frequency signal is inputted to the gate electrode of a 1st FET(field effect transistor) 3, and an inverted input signal is inputted to the gate electrode of a 3rd FET 7. Under such conditions, if the potential of the collector electrode of a 1st negative differential resistance elements 1, the collector electrodes of a 3rd negative differential resistance element 5 or the drain electrode of a 5th FET 9 is defined as an output signal, the high frequency of 1/2 input high frequency is obtained as an output signal. Thus, a function that generates various pulse strings from the clock signals is attained in a small number of elements and a simple circuit constitution by making use of the function having the negative differential resistance characteristic.  As a result, the power consumption is reduced and the operating speed is increased for a waveform generation circuit.
