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
  • Magnet position measurement system
  • High-end audio wireless loudspeaker system
  • 100W high-end audio dynamic class AB power amplifier
  • Analog MEMS system processing 600GB/s with less than 10W dissipation
