Title: Resistance-to-frequency converter
IPC: H03K3/0231
Filed: 1973-02-26
Abstract: 1385660 Frequency determining; measuring temperature PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Feb 1973 [1 March 1972] 9280/73 Headings G1N and G1U [Also in Division H3] A pulse oscillator comprises a bridge basically as shown arranged in the feedback path of an amplifier whereby the period of an oscillation is proportional to the logarithm of the variable ratio between R 1  and R 2 . In operation the capacitor C changes until its potential causes the output voltages of the amplifier to switch, whereupon charging is effected in the opposite sense until the amplifier capacitor voltage switches it back. If one of the resistors has a value expotentially related to a variable, such as a semi-conductor temperature sensitive element, the frequency may thus be proportional to temperature. The output may be connected to an analogue or digital signal producer.
