Switched-current is a new analogue sampled-data signal processing technique that has some limitations. Analyzing the non-ideal factors which influenced the switched-current circuit, it offers a new improved circuit using negative feedback technology against the grid error and switch clock feed of switched-current circuit. The circuit’s simulation in Pspice software environment using 3.3V power supply voltage and 5 MHZ clock frequency showed that the new circuit error is small and the output waveform is ideal.
