Gate Drive Transformer Design: Topology, Selection, and Layout Considerations
Gate drive transformers look simple until a MOSFET dies for no obvious reason. This post covers the volt-second product constraint, core selection, reset methods, winding technique, and the three mistakes that actually kill designs.

Gate Drive Transformers in High-Power Switching Supplies: When and Why to Use Them
Driving the gates of high-side MOSFETs and IGBTs in isolated topologies requires getting a signal across a voltage barrier that can be hundreds of volts. Gate drive transformers are often the most robust and cost-effective way to do it.

Indoor Positioning with BLE: Using Multiple Receivers to Triangulate a Phone's Location
GPS does not work indoors. BLE-based positioning does — but building a system that is actually accurate requires understanding the physics of radio propagation, the math of trilateration, and the practical realities of deploying fixed infrastructure in a real building.

Maximizing Battery Life in Embedded Systems: It's Harder Than It Looks
Getting an embedded device to run for months or years on a coin cell requires more than putting the processor to sleep. Here is what the engineering actually looks like.

Estimating LVEDP from a PPG Signal: Feasibility, Signal Processing, and the Path to a Regulated Device
Left ventricular end-diastolic pressure is one of the most clinically meaningful hemodynamic parameters — and one of the hardest to measure without a catheter. Here is what the engineering looks like when you try to extract it from a photoplethysmography waveform.

Why Revision Control Is Non-Negotiable in Medical Device Software Development
Version control is not just a best practice for medical device software — it is a regulatory requirement that directly supports your design history file, audit trail, and ability to respond to field issues.

STM32 in Medical Device Development: What You Need to Know
The STM32 family is one of the most capable and cost-effective choices for medical device firmware — but using it in a regulated product requires more than just writing good code.
