When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...

Logic level shifting may be required when interfacing legacy devices with newer devices that use a smaller geometry process. For bidirectional bus systems like the I2C-bus, such a level shifter must ...

Level-shifters are an indispensable circuit in multi-power-domain SoCs. Many techniques and architectures have been proposed to enhance the performance of these circuits. Inverter-based level shifters ...

Voltage level shifters are pivotal components in modern CMOS integrated circuits, facilitating robust interfacing between domains operating at disparate voltage levels. Recent advancements in this ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...

If your introduction to digital electronics came more years ago than you’d care to mention, the chances are you did so with 5V TTL logic. Above 2V but usually pretty close to 5V is a logic 1, below ...

Multi-voltage designs are increasingly common in ICs for mobile devices, but can be difficult to implement. The design flows for multi-voltage architectures are inherently complex and present many new ...
