This paper presents an integrated monolithic voltage-mode DC-DC boost converter with low-power control circuit. With the integration of both power switches and control circuit within same CMOS technology, the DC-DC boost converter offers a low-power operation with a small chip-size. The amplifier, oscillator, and comparator in the control circuit are designed with the supply voltage of 3.3V and the...
This paper introduces the design of charge pump DC-DC boost converter with integrated low-voltage control circuit. By exploiting the advantage presented by the integration of both charge pump and control circuit within same CMOS technology, the DC-DC boost converter offers a low-power operation with a proper regulation. The error amplifier, comparator, and oscillator in the control circuit are designed...
This paper introduces the design of integrated BiCMOS current-sensing circuit and amplifier for high-performance DC-DC boost converter. By exploiting the advantage presented by the integration of both CMOS and bipolar devices within same technology, the BiCMOS circuits offers high gain amplifier and accurately sensed inductor current. The error amplifier has BJT differential pair and current sources...
High power device has numerous applications in display and communication systems. LDMOSFET (lateral double-diffused MOSFET) is suitable for these applications because of their high blocking voltage, low on-resistance, and high frequency performance. The basic operation of LDMOSFET [1–2] is similar to that of any MOSFET. However, the drain-source blocking voltage is in the range of 100 volts, and the...
