The design and laboratory tests of a high voltage driver with programmable output current are presented. The proposed solution is designed to work in the range of low frequencies (PWM output current up to 100 KHz) and with output currents between 50 mA and 130 mA. The presented topology exploits a feedback loop that allows fixing the output current to the desired value with high precision not easy...
The design of a high voltage fully differential driver in a 0.18 mum Bipolar-CMOS-DMOS (BCD) technology for the actuation of a double axis scanning micromirror is presented. The proposed circuit has a driving voltage capability up to 25 V and a low Total Harmonic Distortion in order to prevent the excitation of unwanted micromirror's higher resonating modes. This design features a low voltage input...
