  • Publication number: 20240088224
    Abstract: A semiconductor structure includes a first gate structure, a second gate structure coupled to the first gate structure, a source region, a first drain region, and a second drain region. The source region is surrounded by the first gate structure and the second gate structure. The first drain region is separated from the source region by the first gate structure. The second drain region is separated from the source region by the second gat structure. A shape of the first drain region and a shape of the second drain region are different from each other from a plan view.

  • Publication number: 20180205389
    Abstract: A pipelined analog-to-digital converter (ADC) and an operating method are provided. The pipelined ADC includes a multiplying digital-to-analog converter (MDAC) and a sub-ADC. The MDAC alternatively operates in an amplifying phase and a sampling phase according to two non-overlapping clocks, and performs operations on an input signal in the amplifying phase according to a target voltage determined by a digital code. The sub ADC includes multiple comparators, a determination circuit, and an encoding circuit. The comparators generate multiple comparison results by comparing the input signal with multiple predetermined voltages. The determination circuit generates multiple comparison completion signals in a non-overlapping interval of the two clocks according to the comparison results. The comparison completion signals respectively indicate whether the comparators complete the comparison. The encoding circuit determines the digital code according to the comparison results and the comparison completion signals.

  • Publication number: 20160271380
    Abstract: A microneedle applicator. The applicator can include a microneedle array, a microneedle array holder, and an actuator movable between a first position and a second position to cause the microneedle array holder to move, respectively, between a retracted position and an extended position. The applicator can further include a first biasing element configured to bias the actuator in the first position, and a counter assembly, or mechanism, configured to count a number of times the microneedle array holder is moved between the retracted position and the extended position (or the number of times the actuator is moved from the first position to the second position). In some embodiments, the counter assembly can include the actuator and first biasing element.
