摘要: A thermal sensor providing simultaneous measurement of two diodes. first diode and a second are coupled to current source source, respectively. The ratio the currents provided by sources is accurately known. voltage across each diodes may be input differential amplifier for determination temperature. Alternatively, resistor with known drop, an adjustable source. in adjusted until equal sum drop resistor. Under established conditions, Diode Equation used calculate
