Home Made Circuits and Schematics

The V CC is given to the collector of the transistor. The circuit diagram of a basic ramp current generator is as shown here under. A transistor connected in common-base configuration has its collector current vary linearly with its emitter current. This article is about a triangular wave generator The circuit uses an opamp based square wave generator for producing the square wave and an opamp based integrator for integrating the square wave. The circuit diagram is shown in the figure below. A monitor circuit for monitoring a clock signal is described. In accordance with one example of the disclosure, the monitor circuit comprises a pulse generator timing diagrams illustrating example waveforms of the clock signal and the ramp signal In many electronic circuit applications a delay of a few seconds or minutes becomes a crucial requirement for ensuring correct operation of the circuit. Without the specified delay the circuit could malfunction or even get damaged. (c) Ramp Generator There are a lot of circuits using 555 Timer IC. To know more about it, the block diagram must be explained in detail multivibrator 555 timer oscillator circuit 555 timer ramp generator Though they are used in other electronic circuits, they are Q.3. (a) What is a precision rectifier? Explain the operation of a full wave precession rectifier with suitable circuit diagram. (b) Design a Ramp generator with fo= 1.5 KHz and Vo (pp)= 5V . (c) Explain the working of clamper circuits. Q.4. Write short .

The IC 555 can also be used effectively for generating sine equivalent PWMs, by incorporating its built-in opamps and an R/C triangle ramp generator circuit. The following it out with the help of the following diagram, and simulation. Code No: V0421 SET - 1 II B.Tech II Semester (R07) Regular/supply Examinations, Apr- 2010 PULSE AND DIGITAL CIRCUITS duration of the ramp signal. 2. a) List out the types of clamping circuits used in the industry. Give the circuit diagram of each By following the previous equation for 250 V and 100 V, we can obtain: The PWM generator of the flyback circuit was simulated using Proteus simulation suite. Fig. 13 shows the digital simulation diagram of the Silego GreenPAK ramp generator (i.e Practical supplies can be constructed by using resonant inductor circuits to approximate the constant output current and the linear voltage ramp with sinusoidal signals are generated so that the power clock generator can always drive a constant .
