A very simple linear folding architecture for subranging ADC is presented. The preprocessing analog structure is constituted with 2n (with n number of bits) parallel circuits made with a simple subtracting node and with a series of two MOS switches able to join the functionalities of DAC, summing node and amplifier typical of classical subranging ADC. To validate the idea an accurate simulation of the single channels and of the whole structure has been realized.
