ABSTRACT:
A transfer function generator which generates an output that is a cubic function of the input for use in low voltage, high frequency applications. The cubic function generator creates a signal path through high speed npn devices, thereby allowing the use of high frequencies. Further, the topography of the cubic function generator requires a voltage drop across only two semiconductor devices, thereby allowing use of the circuit in low voltage applications.
