Suppose a silicate n+ resistor with a value of 100 Q is used. using the data from Table 4.1, sketch the layout and cross-sectional views of the resistor. The current in the resistor flows mainly in the silicate. Suppose the mobility of free carriers in the silicate is constant with increasing temperature. Would the temperature coefficient of the resistor be positive or negative? Why?
