- Figure 1. The circuit combines ideas from two earlier IFDs to implement a simple, linearized thermal anemometer. An ambient-temperature-compensated device, it is robust and power-efficient
- Figure 2. The quadratic relationship between IQ and Q1/Q2's power dissipation does a fair job of canceling nonlinearity, erasing all but ±5% FSR linearity error over the range of on-scale airspeeds
