WebThe BJT is quite often used as a Low Noise Amplifier due to its low cost. With a minimal number of external matching networks, the BJT can quite often produce an LNA with RF performance considerably better than an MMIC. Of equal importance is the DC performance. Although the device’s RF WebBJT-based temperature sensors are widely used due to their high accuracy over a wide temperature range with a low-cost 1-point trim. Although resistor-based sensors can achieve better energy efficiency, they typically require a 2-point trim to achieve comparable accuracy, while thermal-diffusivity based sensors achieve superior accuracy at the cost …
