| Zusammenfassung | AC-DC thermal converters are fabricated by depositing thin-film heaters on thin dielectric membranes on a silicon chip and by remotely sensing their temperature with radiation sensors through infra-red transmissive fibers. This permits all degrees of freedom for the design of the heater for optimum frequency response. In the present design the sensitivity is quite small. With a temperature of the heater 100 K above ambient, only 5 μW heats up the black spot target of the radiation sensor, resulting in an output voltage of 1.5 mV. The standard deviation of the mean of an ac-dc voltage transfer involving 12 measurements is approximately 20 × 10-6 to 50 × 10-6. |
