Why DAC and ADC responses droop
Have you ever experienced unexpected droop when you’ve plotted out the frequency response of a signal processing system when you expected that the frequency response would be flat?
What to consider in regard to switching frequency
Switch-mode power supplies switch with a frequency that is either fixed, adjustable, or synchronized to an external clock. The value of the switching frequency determines the physical size and, accordingly, the cost of a supply's capacitors and inductors...
Upper end limitations of a duty cycle
The duty cycle of a switching regulator depends on the respective switching regulator topology...
New I3C bus expanders for control plane designs
Renesas Electronics unveiled four new I3C Basic bus extension products for control plane designs across a variety of applications, including data center and server applications, as well as enterprise, factory automation, and communications equipment. The new products include the IMX3102 2:1 bus multiplexer, IMX3112 1:2 bus expander, and IXP3114 and IXP3104 1:4 general-purpose IO expanders, […]
Designing a fast reacting feedback system for miniaturized motor driven designs
A high speed, high throughput ADC accurately captures information and feeds motor position data to the controller, enabling higher levels of accuracy and optimization in the position-feedback system...
A Critical Short Pulse
While there are maximum limitations of a duty cycle, which will be discussed separately, this power management tip focuses specifically on the minimum limitations of a duty cycle.
Quiet and efficient switching regulators
A major challenge for numerous applications is the interference inherent to a switching regulator because it can generate both conducted emissions, typically input-side and output-side, and radiated EMI...
Improving haptic feedback with piezoelectric transducers
Introduction to piezoelectric haptics provides the pros and cons of each and details piezoelectric transducer principles, theory, and modelling along with a proprietary energy recovery process that greatly reduces input power requirements...
Common op-amp circuits
These common op-amp circuits are useful for amplifying various analog signals. The ideal op amp model helps us understand how these circuits operate...
The Ins & Outs of Generalised Impedance Converters
OK, settle down at the back of the room, gentlemen and ladies! I’m back, and there’s more work to do to actually make some filters.
