Nonlinear Electronics 2: Flip-Flops, ADC, DAC and PLL deals with the appearance of nonlinear electronic circuits and their behavior. The book covers a number of circuits that interface between analog and digital electronics, such as astable, monostable, biostable, Schmitt trigger, analog-to-digital conversion and digital-to-analog conversion. In addition, the book deals with all aspects of these circuits, starting from discrete component and gradually going to the integrated circuit.- Presents non-linear electronic circuits and their behavior- Talks about relaxation oscillators- Treats subjects from the discrete element to the integrated device-- Presents interface circuits, analog-to-digital conversion, analog-to-analog conversion, and PLL (phase locked loop)

Flip-flops

Abstract

“Flip-flops” or latches are widely used circuits. There are various applications: for example, delaying the extinction of a signal, pacing the switching on or off of light, dividing the signal frequency, shaping a signal masked by noise, scheduling the operation of a process, processing the signals, etc.

1.1 Overview of the different types of flip-flops

“Flip-flops” or latches are widely used circuits. There are various applications: for example, delaying the extinction of a signal, pacing the switching on or off of light, dividing the signal frequency, shaping a signal masked by noise, scheduling the operation of a process, processing the signals, etc. The flip-flops of greatest interest can be identified as:

• - monostable flip-flops;
• - bistable flip-flops;
• - the Schmitt flip-flop.

Briefly, a monostable flip-flop can be represented by a black box (Figure 1.1). When impulses (so-called trigger pulses) are applied on the input of this device, we will have a signal on output which will alternatively have a quasi-stable and a stable state.

Figure 1.1 Monostable principle

The duration of the quasi-stable state is chosen by the user. At the end of the duration of this quasi-stable state, the circuit returns to its stable state. The quasistable state is obtained on output only if a pulse trigger is sent at the input of the circuit. It should be noted that there are two types of monostable: ret...
