Abstract
Provided are a receiving circuit including a balun circuit and a notch filter, and an operating method thereof. The receiving circuit includes a transformer, a notch filter, and a mixer. The transformer converts a single input signal to a differential input signal using a first tap. The notch filter blocks a specific frequency band of the single input signal by connecting a second tap with the first tap of the transformer using a condenser.
