Logic Families : Circuit concepts and comparison of logic families : TTL, CMOS NMOS and ECL; characteristic parameters : logic levels/fan-in and fan-out, noise margin, propagation delay and power consumption.Minimization of Boolean Functions using (i) Karnaugh Map having don't care entries and (ii) tabular method.Arithmetic Logic Circuits : Representation of negative numbers, 9's and 1's complements 10's and 2's complements, arithmetic using 2's complements. Adders and Subractors, magnitude comparator.Combinational Logic Circuits : Multiplexers / Demultiplexers, encoders/decoders, PAL and PLA.Sequential Logic Circuits : Latches and Flip-Flops : SR, D, T, JK and Master-slave Jk.Shift Registers : Basic principle, serial and parallel data transfer, shift left/right register, universal shift register.Counters : Mode N counters, ripple counters, synchronous counters, ring and Johnson counters.Memories : Read Only Memories ; Random Access Memories; Static and dynamic; sequential memory : Memory Organisation.Linear Wave Shaping : RC low pass and high pass circuits and response to sine and square wave inputs, RC circuit as differentiator, integrator and compensated attenuator.Converters : Sample and hold circuit, A/D and D/A converters.NMOS and CMOS are widely used in the digital ICs, but PMOS ICs are no longer part of new designs. 1.5 NMOS In this section- we will see some basic NMOS logic circuits. 1.5.1 NMOS Inverter Fig. 1.34 shows the basic NMOS inverter circuit.
