Abstract: A voltage controlled oscillator (VCO) is disclosed. The VCO includes an amplifier that receives a control signal and a feedback signal and generates an amplified output signal based on the difference between the control signal and the feedback signal. The VCO also includes circuitry to generate an oscillating output signal based on the amplifier output signal. Additionally, the VCO includes a feedback amplifier that generates the feedback signal based on the output of the amplifier. The feedback amplifier includes a first resistor connected in parallel with a second resistor, the second resistor having an adjustable resistance.

Abstract: A ballistic material utilizes a three-dimensional, square-based pyramid unit cell (SBPUC) sphere structure that includes four base spheres and a primary sphere, which are tightly packed and in contact with each other. The base spheres and the primary sphere are arranged whereby the centers of each of the base spheres form corners of a square base, while the center of the primary sphere forms an apex, which when connected to the corners, forms an imaginary pyramid. The ballistic material is formed from one or more layers of SBPUCs that are provided between a pair of spaced substrate layers, so as to achieve the desired level of ballistic protection performance.

Abstract: A digital-analog converter (DAC) comprises a receiving circuit configured to receive an input bit stream and generate a first bit signal stream of the input bit stream, a first delay circuit coupled to the receiving circuit to receive the first bit signal stream and to generate a second bit signal stream representing a delayed version of the first bit signal stream. The DAC also comprises a first current generation circuit to receive the first bit signal stream, the first current generation circuit configured to provide first current, corresponding to the first bit signal stream, to a first output. The DAC further comprises a second current generation circuit to receive the second bit signal stream and to provide second current to the first output responsive to receiving the second bit signal stream, a waveform of the second current inverted and scaled relative to a waveform of the first current.
