In the last decades, the complexity of embedded systems has been increasing continuously thanks to the industrial improvements in nanometric CMOS technologies, that allow the integration of hundreds of Intellectual Property cores on a single chip die. This process has been favored by the trend towards design of reusable and configurable components that can be utilized across different chips. In such...
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...
This paper presents the design and the laboratory results of an integrated half-bridge driver for power electronic systems in a 0.35 mum bipolar CMOS DMOS (BCD) technology. The proposed solution is designed for frequency applications up to several hundred of KHz and it has a driving current capability up to 50 mA. This work features a design configuration and a digital control to reduce electromagnetic...
