Editor's note: We will publish this article in four sequential parts leading up to our “Ask the experts” session on Precision Voltage References on May 21. Alan Walsh will be one of our experts. The ...

Applications sometimes require the generation of a voltage that is below the reference rail. Many design engineers would just use a second regulator to generate this voltage. However, a simple change ...

CT20307 is an accurate reference voltage generator. In order to achieve a total error <2%, the amplifier in the bandgap core block implements an of ...

The ODT-REF-SV1P2-4T is a high-performance reference current and voltage generator. The block incorporates a proprietary architecture to achieve high ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

In analog and mixed-signal circuits, the voltage reference acts as the standard against which other signals are measured. Inaccuracy and variation in the voltage reference directly impact the accuracy ...

Voltage references are available with fixed and adjustable reference voltage outputs. Adjustable output is set by a resistor divider connected to a reference pin. These references are either shunt ...

Many embedded systems require a stable, low-noise DC reference. This reference can be a stable current or voltage source. These references are used in many ways. Some typical uses are listed as ...
