A 14-V high speed driver in 5-V-only 0.35-/spl mu/m standard CMOS

Abstract

A high-voltage and high-speed driver, using only 5-V and 3.3-V technology features in 0.35-/spl mu/m standard CMOS, is presented. The pull-up function is performed by cascaded 5-V PMOS; a 5-V CMOS compatible gate-shifted LDD NMOS performs the pull-down. The maximum continuous operating voltage is 14 V. The driver is suitable for inductive and capacitive loads. An external MOSFET with 1 nF gate capacitance is fully switched in 200 ns, the peak current that the driver delivers is more than 100 mA. The area of the driver including pad is 0.18 mm/sup 2/. The paper discusses characteristics and lifetime of the driver transistors, design trade-offs, and presents simulations, measurement results and statistical data.
