Abstract
A sampling circuit and a receiver, with relatively simple configurations, and clocks, exhibiting excellent frequency characteristics, are provided. In discrete time circuits, a charging switch is controlled on and off using one of four-phase control signals. A rotate capacitor shares electrical charge accumulated in an IQ generating circuit via the charging switch. A dump switch is controlled on and off using a different signal from the control signal used to control the charging switch on and off, among the four-phase control signals. A buffer capacitor shares electrical charge with the rotate capacitor via the dump switch to form an output value.
