Projects¶
On-the-job training¶
At this moment several students as well as employees of different companies receive on-the-job training in analog electronics.
Proof of concepts¶
During the past 20 years I developed many analog proof of concepts and helped my customers with the engineering converting them into end products. Here is a selection:
13.56MHz RFID transceiver with class E transmitter power amplifier
Low-noise, high-stability PSD optical position detection system
Programmable class D high-efficiency current driver for three-phase DC motors up to 100W
Multi-mode crystal oscillator with a temperature stability in the ppb range using a standard AT-cut crystal
Programmable class H programmable high-efficiency charge driver for piezo actuators 1nF .. 1 uF +/-250V, 5kHz
Programmable class B charge driver for piezo actuators 5nF … 300nF, +/-250V, 5kHz
Class AB voltage amplifier for capacitive loads 0 … 1nF, +/-250V, > 50kHz
Class AB voltage amplifier for capacitive loads 0 … 2uF, +/-1000V, > 5kHz
Programmable four-quadrant +/-4KV power supply for electrostatic clamps
Temperature compensated multi-mode X-tal oscillator with a temperature stability of +/- 0.2ppm using an AT-cut crystal
136MHz 30W power booster for AM radio communication with high-efficiency class E output stage
