description: This work focuses on the design of switches that are used in switched-capacitor circuits. The aim of the work is to research and design switches with a reduced resistance range. To achieve the aim, the following tasks were solved: - design and simulation of CMOS switch; - design and simulation of a switch with a reduced resistance range; - design of an operational transductance amplifier for switched-capacitor circuits; - simulation the converter of the nonbalance signal into the balance signal using the designed switches; - simulation of the sample and hold device using the designed switches. The work presents circuits of a CMOS switch and switches with a reduced resistance range, as well as the results of simulation as part of the sampling and hold device and the converter of the nonbalance signal into the balance signal. Resistances were measured to evaluate the performance of the switches, as well as the SNR and SFDR of the output signal. Topologies are designed for the circuits. The presented results show the advantage of using the designed switches in comparison with CMOS switches.
