Design of DC-DC Boost Converter in CMOS 0.18µm Technology

Gayatri Vidya Parishad College of Engineering for Women, Visakhapatnam, Andhra Pradesh, India.

A CMOS DC-DC boost converter with fastest settling time and less quiescent current with a feedback control is implemented. An extra path is introduced because of an error amplifier (OTA) which has an effective control for fast response. Efficient compensation with soft-start is used to make the quiescent current low. An on-chip current sensing circuit is introduced with less number of I/O pins for current mode control. In this project, the DC-DC boost converter is designed in Cadence virtuoso 0.18µm technology with a 5V supply. With a wide range of loads, it provides 25V at the output, 50mA load current with 90% efficiency. The circuit is operated at 500 KHz clock frequency with output ripple voltage of 20mV by using 4.7µF off-chip capacitor and 75µH off-chip inductor.

Important Announcements

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
