Abstract: An active quadrature generation circuit configured to provide an in-phase output signal and a quadrature output signal based on an input signal and a method of fabricating the active quadrature generation circuit on an integrated circuit are described. The circuit includes an input node to receive the input signal and a first transistor including a collector connected to a power supply pin. The circuit also includes a second transistor including a base connected to the power supply pin, the second transistor differing in size from the first transistor by a factor of K, wherein the in-phase output signal and the quadrature output signal are generated based on an inherent phase difference of 90 degrees between a current at a collector of the first transistor and a current at a base of the second transistor.

Abstract: A single-to-differential converter and a method of fabricating the single-to-differential converter on an integrated circuit are described. The single-to-differential converter provides a pair of differential outputs based on a single-ended input and includes an input node to receive the single-ended input, and a first transistor connected to a power supply pin. A second transistor is connected to the power supply pin. The first transistor and the second transistor are biased under a same amount of direct current (DC) and the pair of differential outputs are generated at respective collectors of the first transistor and the second transistor.
