An ultrasonic sensor circuitrequiring self-adjustment to thelevel of an ac-input signal also mustaccommodate the signal’s unknownand variable dc-bias voltage. The circuitcannot use an ac coupling ...

Today’s integrated video filter/driver devices can be designed into video systems (set-top boxes, PVRs, TVs) using a wide range of coupling and clamping configurations, such as input ac- or ...

Why should we do AC-coupling on SDI and, how does AC-coupling degrade our SDI signal? In past experiences, many engineers asked me this simple question, and because we are familiar with AC-coupled ...

Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...
