When MOSFET is used as a power switch, it is essential to prevent reverse current flow through the parasitic body diodes under reverse voltage condition. A new built-in reverse voltage protection circuit for MOSFETs has been developed. In this design

A novel dynamic-floating-gate technique is proposed to improve ESD robustness of the CMOS output buffers with small driving/sinking currents. This dynamic-floating-gate design can effectively solve the ESD protection issue which is due to the differe

Due to the large number of output buffers on a column driver chip of a flat-panel display, the quiescent current and die area of the output buffer must be minimized. This paper presents a low static power, large output swing, and wide operating volta

A separately self-biased transistor-transistor logic (TTL)-to-CMOS input buffer (SSIB) is proposed. Its logic threshold voltage is kept at 1.4 V when supply voltage is changed from 3.3 V to 5 V, making it suitable for 3.3-V/5-V dual voltage applicati

A high-speed complementary metal-oxide-semiconductor (CMOS) programmable divide-by-N frequency divider was proposed. Using a new end-of-count (EOC) detecting and reloading algorithm, the reloading delay is distributed over three clock cycles, which i

Conventional charge pump circuits use a fixed switching frequency that leads to power efficiency degradation for loading less than the rated loading. This paper proposes a level shifter design that also functions as a frequency converter to automatic

A fully integrated CMOS temperature sensor is presented. The design uses parasitic substrate bipolar transistors as a temperature sensor. The temperature and reference signals are first converted into current signals by a voltage-to-current converter
