SNOSC11B – AUGUST 2000 – REVISED MARCH 2013

Figure 71. Output Voltage has Negative Temperature Coefficient (TC) if R2 has Negative TC

Figure 72. Output Voltage has Positive TC

if R1 has Negative TC

Figure 73. Diode in Series with R1 Causes Voltage Across R1 and R2 to be Proportional to Absolute

Temperature (PTAT)

Connecting a resistor across Cathode-to-FEEDBACK creates a 0 TC current source, but a range of TCs may be

synthesized.
