Latest Patents

Jun Ho Cho holds a patent for an "Output buffer with controlled slew rate for driving a range of capacitive loads." This invention minimizes output buffer slew rate variation over changes in load capacitance by dividing output voltage transitions into distinct time and output current segments. During the initial time segment, the first drive stage with the smallest current is utilized. After specific delays, additional drive stages are activated, and the load current is sequentially increased. Each drive stage incorporates a specifically sized feedback device, which can either introduce parasitic capacitance to slow transitions or provide positive feedback to accelerate them. The initial stages are designed to include parasitic capacitance, resulting in minimal changes in the settling time for small capacitance loads compared to prior art output buffers. The latter stages employ positive feedback to enhance transition times, significantly improving settling time for larger load capacitances.
