Abstract :
A low voltage current mode sample and hold (S/H) in 0.18 μm technology with 1.5 V supply voltage is presented. This S/H has 12-bit linearity, i.e., gain and nonlinearity errors of S/H are less than 0.02 μA for 100 μA input current. Maximum sampling rate for this structure is 100 MHz (using double sampling technique).
