With a total of 5 patents to his name, Bugeja continues to push the boundaries of innovation in his field.
Latest Patents
One of Bugeja's latest patents is for a high dynamic linearity current-mode digital-to-analog converter architecture. This invention dramatically reduces dynamic mismatches between different current segments of a segmented current-mode DAC. By providing substantially the same local architecture for each of the individual current segments, the parasitic effects of any physical realization can be controlled. In one embodiment, the most-significant-bit (MSB) current segments and the least-significant-bit (LSB) current segments each have the same number of multiple internal current branches. In the MSB segments, the multiple internal current branches are combined at a source node, whereas, in the LSB segment, a portion of the segment current is dumped, or wasted, through at least some of the internal current branches.
Another significant patent involves circuit architectures and methods for A/D conversion. In this invention, an array of transistor circuits is fabricated so that each transistor circuit in the array has a switching threshold determined by intrinsic switching thresholds of at least one sensing transistor in a corresponding transistor circuit. The sensing transistors in a set of transistor circuits of the array can be fabricated to have common physical dimensions, even though corresponding intrinsic switching thresholds of the transistor circuits can vary. The switching thresholds can vary based on an applied well bias voltage, or alternatively, can be set to a common value with a tapped delay line coupled to the transistor circuits.
