Abstract:
A frequency converter for converting a signal at a first frequency to a signal at a second frequency, said frequency converter including:a. a first input for receiving an input signal at the first frequency;b. a second input for receiving an oscillator signal characterized by a frequency that determines a frequency difference between the first frequency and the second frequency;c. a processing stage coupled to said first input and to said second input, said processing stage including a plurality of transistors associated by pairs, each pair of transistors including a first transistor and a second transistor, each transistor including a gate terminal, the gate terminals of said first transistor and the gate terminal of said second transistor being coupled to one another, the first and second transistors being in a self-biased condition; andd. an output coupled to said processing stage for generating the signal at the second frequency.
