Abstract
An electronic circuit is provided. The electronic circuit includes an input port configured to receive an in-phase (I) data signal and a quadrature (Q) data signal. The electronic circuit includes a conversion circuit configured to convert the I data signal and the Q data signal to a plurality of differential signal pairs. The electronic circuit includes a mixer circuit configured to mix the plurality of differential signal pairs with a plurality of pulse signals to obtain a pair of differential mixer output signals. The electronic circuit includes a variable gain amplifier (VGA) configured to generate an output signal based on the pair of differential mixer output signals. The plurality of pulse signals have a same duty ratio that is greater than where N is a total number of the plurality of pulse signals. A phase difference between two consecutive pulse signals equals Also provided is a method.
