Square wave oscillators and Op-amp square wave oscillator.

Square wave oscillators If Fourier analysis is performed on a square wave it is found that the waveform is composed of many harmonics of the fundamental frequency. This rich harmonic content makes the square wave particularly useful as a quick test of amplifier performance. Examples of possible results are shown. The simplest way to produce a square wave is to make a sine wave oscillator in one of the ways described earlier, then feed the output to some form of squaring circuit such as a Schmitt trigger. This is the method adopted in most commercial sine/square wave generators. There are, however, several circuits for square wave oscillators and a description of the most common follows. Multivibrator Technically the multivibrator is a relaxation oscillator, working on the charging of a capacitor through a resistor. If a negative edge is applied to the circuit in (a), transistor TR 1 turns off the for time taken for the base voltage to return to 0 V. If the voltage step is

Carry Look-Ahead Adder As previously stated, the carry, c i +1, produced at the i -th position is calculated as c i +1 = x i · y i ∨ c i ·( x i ⊕ y i ). This means that a carry is generated if both x i and y i are 1, or an incoming carry is propagated if one of x i and y i is 1 and the other is 0. Therefore, letting g i denote x i y i , we have c i +1 = g i ∨ c i p i , where p i = x i ⊕ y i . Here, g i is the formula for the carry generation condition at the i -th position, i.e., when g i is 1, a carry is generated at this position. Substituting g i –1 ∨ p i –1 c i –1 for c i , we get A carry look-ahead adder can be realized according to this expression, as illustrated in Figure 41.10 for the case of four bits [21]. According to this expression, c i +1’s are calculated at all positions in parallel. It is hard to realize an n -bit carry look-ahead adder precisely according to this expression, unless n is small, because maximum fan-in and fan-out restriction is violated at higher
