摘要
PURPOSE: A discrete time filter device and a discrete time receiver system including the same are provided to adjust the order of a filter and decimation ratio, by adjusting the period of a clock and delay time between clocks. CONSTITUTION: A number of current supply units generate a current. The current has the amplitude obtained by multiplying the amplitude of an input current by a gain. An adder adds the current supplied from the current supply units. A number of control parts interlink the current supply units and the adder. The control part controls the flow of the current supplied from the current supply unit to the adder. The current supply unit includes a current mirror structure. The input current is inputted to one end of the current mirror structure.
