Precise Voltage to Frequency Converter for Telemetry Applications of Strain Gage Pressure Transducers
Thomas P. Grover · IEEE Transactions on Biomedical Engineering · 1975
A voltage to frequency converter suitable for telemetric applications of strain gage pressure transducers is described and analyzed. The circuit uses a voltage reference IC and a temperature dependent op amp bias current to achieve zero pressure offsets less than 3 torr over a 25°C temperature range and a 1 volt supply voltage range.
