To test products in my R&D lab, I build many universal data-acquisition systems that connect to a PC or another controller through RS-232 links or LANs. These small systems typically include multiple ...
A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...
An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...
As the number of Power Over Ethernet (PoE) powered device (PD) applications grows, market pressures are driving designers to lower the cost and complexity of the DC-DC converters that power them, ...
How to decide between buffered and un-buffered (switched capacitor), high-speed analog-to-digital converters, with an example of anti-aliasing filter design. The fundamental end goal when using an ADC ...
