Current-mode design topology [] was also used rather than a voltage-mode approach. Preamplifiers with exactly the same circuit layout were fabricated using µm and two different µm.Transfer resistance amplifiers using standard operational amplifiers are often employed when moderate bandwidths and low noise are required from capacitive current sources, such as photodetectors for optical imaging and the samples which are used in the OBIC and EBIC techniques of semiconductor microscopy.
