Supply voltage supervisors have found their solid place in digital systems. They monitor the system's supply voltage and ensure a correct initialization of the circuits connected. The trend with digital integrated circuits with extremely low current consumption requires an equivalent reduction of the power dissipation of analog circuits. This report describes an advanced supply voltage supervisor

A switching power supply consists of the power stage and the control circuit. The power stage performs the basic power conversion from the input voltage to the output voltage and includes switches and the output filter. This report addresses the buck power stage only and does not cover control circuits. Detailed steady-state and small-signal analysis of the buck power stage operating in continuous

Enabling High Current Hotswap Applications using the TPS2393A Written by Chinese speaking engineer

The VCA8617 is an 8-channel variable gain amplifier ideally suited for portable and mid-range ultrasound applications. Each channel consists of a Low Noise Amplifier (LNA) and a Variable Gain Amplifier (VGA). The VGA contains two parts: a voltage-controlled attenuator (VCA) and a programmable gain amplifier (PGA). The PGA output feeds directly into an integrated 3-pole low-pass Butterworth filter.
