    摘要: Provided is a discrete time receiver having a structure capable of processing various broadband signals. The discrete time receiver uses a discrete time filter having a sampling frequency in a constant range so as to process a signal having an input frequency in a wide range and a wide bandwidth, so that it is possible to reduce current consumption and the area of the discrete time receiver. Since the discrete time receiver is easily integrated with a digital device, it is easy to design a chip using system on chip (SoC).
