- 1. OPERATIONAL AMPLIFIERS AND LOGIC GATES A BRIEF DISCUSSION
- 2. OPERATIONAL AMPLIFIERS <ul><li>Linear integrated circuits are being used in a number of applications such as fields like communication, medical electronics, instrumentation control </li></ul><ul><li>An important linear IC is operational amplifier </li></ul>
- 3. <ul><li>OP-AMP is a solid state device capable of sensing and amplifying dc and ac input signals. </li></ul><ul><li>OP-AMP is an amplifier with two inputs and a single output. </li></ul><ul><li>OP-AMP consists of 20 transistors, 11 resistors and one capacitor. </li></ul>
- 4. INVERTING AMPLIFIER <ul><li>The input voltage is applied through the V s to the inverting input through the input resistor R S </li></ul><ul><li>Here I s= I f </li></ul><ul><li>The output voltage is out of phase with the input voltage </li></ul>
- 5. NON-INVERTING AMPLIFIER <ul><li>The input signal is applied through v g </li></ul><ul><li>The resistor R s is connected from the inverting input to ground. </li></ul><ul><li>The feedback resistor R f connected between the output and the inverting input. </li></ul><ul><li>Here the input and output voltages are in phase. </li></ul>
- 6. SUMMING AMPLIFIER <ul><li>An inverting amplifier, used to sum two input voltages. </li></ul><ul><li>The output is –(V 1 +V 2 ) </li></ul><ul><li>The output voltage is equal to the sum of the input voltages and the circuit acts as a summing amplifier. </li></ul><ul><li>The negative sign indicates that OP-AMP is used in the inverting mode. </li></ul>
- 7. DIFFERENCE AMPLIFIER <ul><li>The output voltage can be obtained by using superposition principle. </li></ul><ul><li>The output is V 3 -V in </li></ul><ul><li>If all the external resistors are equal, the voltage difference amplifier functions as a voltage subtractor. </li></ul>
- 8. LOGIC GATES <ul><li>Circuits which are used to process digital signals are called logic gates. </li></ul><ul><li>It has one or more inputs with only one output and the output appears only for certain combination of input signals. </li></ul><ul><li>The basic elements that make a digital system are “OR” ,”AND” and “NOT” gates. </li></ul>
- 9. OR GATE
- 10. AND GATE
- 11. NOT GATE
- 12. NAND GATE
- 13. NOR GATE
- 14. EXOR GATE
- 15. LOGIC GATES CAN BE SIMPLIFIED AS…..
