After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be solved.

Here’s a nostalgic vibe of an awesome analog chip from the 1990s era that’s still making an impact in audio designs.

A software suite powering oscillators and clocks claims higher time synchronization accuracy than quartz-based solutions.

There are many options when you need to splice wires. In addition to formal two-piece connectors, there’s the widely used ...

Planet Analog provides an online community for semiconductor and system designers/engineers interested in advancing analog design techniques.

Engineers often use SPICE simulations for operational amplifiers to look at the stability of a proposed circuit. SPICE simulations are particularly frequent for high-speed amplifier applications where ...

Table 2 Loop filter parameters are shown for a down-converted architecture. Source: Texas Instruments Figure 7 shows the measured result and simulation obtained from the LMX2820 chip, which has a ...

The previous blog looked at some of the structures in an analog circuit that are implied by the schematic, but not specified in detail. Key examples of this are well, taps and guard rings. These ...

The first installment of this two-part series focused on debugging brushed-DC motor systems. Now the second installment will share some tips for stepper motor systems and provide general bench testing ...

The tips and tricks when testing motor-driver ICs on the lab bench can help engineers reduce time spent on evaluating and prototyping motor systems. The first installment of this two-part article ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

There are various reasons why you might need to split a voltage rail in your design. Perhaps the design contains a sensor or an IC that requires a bipolar supply, or you need to make the best use of ...
