The design of a high-voltage PWM current driver for hot-wire anemometers is presented. The circuit is able to provide a PWM output current whose value can be fixed by means of a negative feedback loop. The circuit will be used, together with other analog and digital IPs, to perform a constant temperature fluid speed measure based on a hot-wire anemometer. The proposed solution has been designed and simulated in a 0.35 μm Bipolar-CMOS-DMOS technology.

Abstract
The design of a high-voltage PWM current driver for hot-wire anemometers is presented. The circuit is able to provide a PWM output current whose value can be fixed by means of a negative feedback loop. The circuit will be used, together with other analog and digital IPs, to perform a constant temperature fluid speed measure based on a hot-wire anemometer. The proposed solution has been designed and simulated in a 0.35 μm Bipolar-CMOS-DMOS technology.File in questo prodotto:
