Abstract
A direct sampling circuit and a receiver which carry out discrete time analog processing with a high degree of design freedom and are provided with a filter property which is achievable to comply with the receipt of a broad band signal. A plurality of discrete time analog processing circuits () are connected in parallel with each other, a gm value and a capacitance of a capacitor in each circuit system are set independently based on a prescribed condition, and an output signal obtained from each circuit system is synthesized by means of a buffer capacitor (), so that an equivalently high-dimensional IIR filter can be put into practice.
