Mike DonnellyThis simple "Joule Thief" self-oscillating LED circuit will produce light even when the battery voltage drops to 0.4 V.

Mike DonnellyThis is a companion example to the design: "TDFS Impedance Stability of Transmission Line Fed LED Driver - Switching".

Mike DonnellyThis example demonstrates the use of the TDFS method (Time Domain Frequency Sweep) to measure impedance stability ratio.

Mike DonnellyThis LED Dimmer Circuit uses a 555 Timer to control the PWM duty cycle of the current drive.
