A 14b, 150ns Sample-and-hold Amplifier With Low Hold Step

Sample-and-hold amplifiers with attractive features such as time under 200ns to 0.01 % of 10V step, hold step under±5mV, and accuracy over 12b have traditionally been implemented in hybrid technologies and are expensive.1 The increasing demand for high-resolution and high-speed analog-to-digital conversion has stimulated development of a monolithic sample-and-hold amplifier with performance comparable to that of hybrid counterparts.
