The sensor 12 thus constructed is inserted as a resistor, which is operative to determine the frequency of a resistance-frequency converting circuit, into this circuit. This circuit is composed of two amplifiers 21 and 22. Thus, even if leak resistors 26 and 27 are changed, a sensor resistor...
Now, when the analogue switches 9-11 of an input circuit A are brought to an operation state, a constant current is supplied to the resistors 7, 8 from a constant current circuit 2 through an analogue switch 9 and a resistor 12. The difference of voltage drops generated in the resistors...
Temperature to frequency converter A temperature to frequency converter includes two temperature detectors having an electrical characteristic, such as resistance, that varies proportionally with sensed temperature. These devices are connected into an oscillator circuit t... GH Forehand - US 被引量: 14发...
In this paper we present an integrated wide-range resistance-to-time converter. The circuit in transistor level simulations achieves a precision of about 0.5% over a range of 5 decades (1k惟-100M惟) without requiring any calibration or autoranging. The presented technique exploits an integrator-...
