An anti-log amplifier design with a temperature-compensation network built around a nearly linear PTC thermistor.

We proposed and demonstrated a temperature sensor with both high resolution and large dynamic range based on simultaneous microwave photonic and optical measurements. To simultaneously increase the ...
