Abstract
An analog circuit for the compensation of pressure effects in thermal flow meters is presented. The result is obtained by modulating the power delivered to the heater by means of a feedback loop that senses the pressure variations with no need of an additional pressure sensor. A possible system architecture is proposed and the effectiveness of the method is demonstrated by means of VHDL-AMS simulations.
