The most important feature of the MOSFET operating in the ohmic region, then, is that it acts as a voltage-controlled resistor, with the gate-source voltage, vGS , controlling the channel resistance, RDS The use of the MOSFET as a switch in the ohmic region, then, consists of providing a gate-source voltage that can either hold the MOSFET in the cutoff region (vGS VT ) or bring it into the ohmic region In this fashion, vGS acts as a control voltage for the transistor Consider the circuit shown in Figure 1044, where we presume that vC can be varied externally and that vin is some analog signal source that we may wish to connect to the load RL at some appropriate time The operation of the switch is as follows When vC VT , the FET is in the cutoff region and acts as an open circuit When vC > VT (with a value of vGS such that the MOSFET is in the ohmic region), the transistor acts as a linear resistance, RDS If RDS RL , then vout vin By using a pair of MOSFETs, it is possible to improve the dynamic range of signals one can transmit through this analog gate MOSFET analog switches are usually produced in integrated circuit (IC) form and denoted by the symbol shown in Figure 1045 A CMOS gate is described in 9 in a Focus on Measurements section

You will recall that a diode conducts current when it is forward-biased and otherwise acts very much as an open circuit Thus, the diode can serve as a switch if properly employed The circuit of Figure 1046 is called an OR gate; it operates as follows Let voltage levels greater than, say, 2 V correspond to a logic 1 and voltages less than 2 V represent a logic 0 Suppose, then, that the input voltages vA and vB can be equal to either 0 V or 5 V If vA = 5 V, diode DA will conduct; if vA = 0 V, DA will act as an open circuit The same argument holds for DB It should be apparent, then, that the voltage across the resistor R will be 0 V, or logic 0, if both vA and vB are 0 If either vA or vB is equal to 5 V, though, the corresponding diode will conduct, and assuming an offset model for the diode with V = 06 V we nd that vout = 44 V, or logic 1 Similar analysis yields an equivalent result if both vA and vB are equal to 5 V This type of gate is called an OR gate, because vout is equal to logic 1 (or high ) if either vA or vB is on, while it is logic 0 (or low ) if neither vA nor vB is on Other functions can also be implemented; however, the discussion of diode gates will be limited to this simple introduction, because diode gate circuits, such as the one of Figure 1046, are rarely if ever employed in practice Most modern digital circuits employ transistors to implement switching and gate functions
