High-side current sensing is used in a wide range of applications. Usually, it is used for overcurrent protection in power management circuits. On the market, there are many off-the-shelf operational amplifiers that can be used to measure current on the…
A buck converter is a simple type of DC-to-DC converter that produces an output voltage that is less than its input voltage. In other words, this DC-to-DC converter steps down the voltage from its input to its output. Hence, it…
The high-speed photodiode circuit in Figure 1 uses a low capacitance PIN photodiode (PD), load resistance (RL), and a high-speed operational amplifier (U). In this configuration, the photodiode is reverse biased and used in photoconductive mode. The short circuit current…
