1. An operational amplifier (op-amp) configurable in a non-inverting mode with a closed loop gain greater than one, and with correction in an output signal of the op-amp for a time varying voltage reference of the op-amp relative to a true voltage reference, the op-amp comprising: a ...
MACROMODELS AND APPLICATIONS SUPPORT Computer simulation of circuit performance using SPICE is often useful when analyzing the performance of analog circuits and systems. This is particularly true for video and RF amplifier circuits where parasitic capacitance and inductance can have a major effect on ...
Figure 3 shows a pair of LT6552s connected as inverting and non-inverting unity-gain stages to form a balanced gain-of-two differential amplifier. The input cable is differentially terminated with 75Ω (as for camera video on coax), and the outputs are each back-terminated in half ...
