Figure 3.2 Block Diagram of Temperature Monitoring Circuit

Figure 3.2 shows a block diagram of the temperature measurement circuit. The negative terminal for

the remote temperature diode, DN, is internally biased with a forward diode voltage referenced to

ground.

The External Diode 2 channel in the EMC1063 is compatible with a broad range of thermal diode,

including those found in AMD processors, that may be connected as shown in Figure 3.3.
