摘要： A method for determining the position of a target is provided. Several emitted pulses of terahertz radiations are emitted from a phased array (which has several transceivers) in consecutive cycles (typically). These emitted pulses are generally configured to be reflected by a target so as to be received by the phased array within a scan range (which includes a digitization window with several sampling periods). Output signals from each of the transceivers are then combined to generate a combined signal for each cycle. The combined signal in each sampling period within the digitization window for emitted pulses is averaged to generate an averaged signal for each sampling period within the digitization window. These averaged signals are then digitized.

摘要： At very high frequencies, generally above 100 GHz, the performance of traditional radio frequency (RF) circuitry begins to significantly limit performance. An example is the hybrid coupler, which can have a relatively narrow 90° bandwidth in these frequency ranges. Here, however, a branch-line hybrid coupler (which has been integrated into a quadrature downconversion mixer) has been modified. Namely, an adjustable impedance network has been coupled to isolation port (which has traditionally been terminated) to substantially increase the tuning range and expand the bandwidth of the quadrature mixer within these very high frequency ranges.

摘要： A method for providing a plurality of narrow pulses is provided. A first pulse having a first width is received by a delay line having a plurality of delay cells. This first pulse has a first width. In response to this first pulse, a plurality of second pulses is generated by the delay line, where each second pulse has a second width that is less than the first width. First and second delay pulses are also generated by the delay line, and a delay for each delay cell in the delay line can then be adjusted if a rising edge of the second delay pulse is misaligned with a falling edge of the first delay pulse.

摘要： A method for determining the location of an object on a touch panel is provided. Initially, a pulse of terahertz radiation is transmitted through a touch panel, which formed of a dielectric material such that the pulse generates a evanescent field in a region adjacent to a touch surface of the touch panel. A reflected pulse is generated by an object located within the region adjacent to the touch surface of the touch panel, and a position of the object on the touch surface of the touch panel is triangulated at least in part from the reflected pulse.

A first integrator stage receives an input signal and provides an output signal, the integrator stage having a first common-mode reference voltage applied thereto for control of the common-mode voltage of the integrator stage. A second integrator stage receives an input signal and provides an output signal, the integrator stage having a second common-mode reference voltage applied thereto for control of the common-mode voltage of the integrator stage. A comparator stage receives the output of the first integrator stage and the output of the second integrator stage and provides an output signal corresponding to the difference between them.

摘要： Transmission lines employing transmission line units or elements within integrated circuits (ICs) are well-known. Typically, different heights for these transmission line units can vary the characteristics of the cell (and transmission line), and there is typically a tradeoff between impedance and space (layout) specifications. Here, a transmission line is provided, which is generally comprised of elements of the same general width, but having differing or tapered heights that allow for impedance adjustments for high frequency applications (i.e., 160 GHz). For example, a transmission line that is coupled to a balun, with the transmission line units decreasing in height near the balun's center tap to adjust the impedance of the transmission line for the balun, is shown.
