A lot of the analog-circuit conversation these days is centered on low-power and thus low-voltage considerations. That makes sense for operational amplifiers (op amps), of course, since these basic analog building blocks often serve as a buffer or ...
Switching regulators use a duty cycle to realize voltage or current feedback control. The duty cycle is the ratio of the turn-on time (T ON ) to the complete cycle length, the turn-off time (T OFF ) plus on time, and defines a simple relationship ...
Electromagnetic compatibility and oftentimes PCB trace routing are key participants in the switching-regulator hot-loop phenomenon. The term hot loop is relevant whenever switching regulators and their electromagnetic compatibility (EMC) are ...
The flyback topology is a versatile, widely used, switched-mode power-supply design with some interesting characteristics that brings performance and BOM advantages to many applications. The flyback design is a switched-mode power supply (SMPS) ...
David Megaw and Bruce Haug, Analog Devices Design Note Introduction A common dc-to-dc converter problem is generating a regulated voltage when the input voltage can be above, below, or equal to the output that is, the converter must perform both ...
Question: Where should the coil go? Answer: Switching regulators for voltage conversion use inductors for temporarily storing energy. These inductors are often very large components and must be positioned in the printed circuit board (PCB) layout ...
Part 1 Preserved DC Precision In a typical operational amplifier circuit, a portion of the output is fed back to the inverting input (Figure 9). Errors that are present on the output which were generated in the loop are multiplied by the feedback ...
by Jino Loquinario, Analog Devices Analog Dialogue Introduction It is normal, and almost expected, to be faced with applications for which a solution does not appear to exist. To meet their requirements would require us to think of a solution that ...
For a wide variety of products, manufacturing processes require highly precise and reliable temperature measurement technologies. Temperature is often measured through direct contact with a sensor, for example, through immersion of a sensor in ...
Low quiescent current, also called supply current, might be an important spec for your power-supply design. Quiescent current is the current that a chip needs to operate even if it’s not delivering power. It’s the bare minimum supply ...
