1. An input circuitry for receiving an analog input signal, said input circuitry comprising:
an input transistor, which is configured to receive the analog input signal on a gate terminal of the input transistor;
wherein the input transistor is connected to a digital component providing a digital signal, and wherein the input transistor is configured to receive the digital signal on a bulk terminal of the input transistor;
wherein the input transistor is configured to provide an output current based on the analog input signal and the digital signal, such that the input transistor provides digital-to-analog conversion of the digital signal received on the bulk terminal,
wherein the input circuitry comprises a set of input transistors, wherein each input transistor in the set is configured to receive the analog input signal on the respective gate terminal of the input transistor, wherein each input transistor in the set of input transistors is configured to receive a respective digital signal on the respective bulk terminal based on a unique bit in a multi-bit digital value.
