Thermistor cancels negative resistance of tunnel diode, and calibrated potentiometer that matches thermistor gives absolute value of td resistance at operating point. Q1 pro vides thermistor heating current, at level set by R6, while 5-v, 20-kc source provides ac to modulate bias of tunnel diode.-A.Ambrozy, Thermistor Measures Negative Resistance of Tunnel Diode, Electronics, 39:17, p 95-96.
