High Voltage Converter: 90V From 1.5V
The circuit illustrates a method to obtain a voltage of 90V from a 1.5V battery supply. The LT1073 switching regulator from Linear Technology operates in boost mode and can function with an input voltage as low as 1.0V. The switching...
60kv ignition coil driver circuit
The ignition coil driver circuit described is a highly regarded design, reportedly created by Jochen Kronjaeger. It is intended to operate from a 230V source, although a modified version can function effectively at 120V. The circuit requires two ignition coils...
Diode Sensor For Lasers
Laser-receiver circuits must bias their avalanche photodiodes (APD) to achieve optimal gain. Unfortunately, an APD's gain depends on the operating temperature. The circuit controls the operating voltage of an APD over a large temperature range to maintain the gain at...
