  • Patent number: 11153566
    Abstract: A variable bit rate generative compression method based on adversarial learning is provided. According to the method, a variance of a feature map of an encoding-decoding fill convolutional network is quantized to train a single generative model to perform variable bit rate compression. The method includes the following implementation steps of: constructing training and testing data sets through an image acquisition device; constructing a generative compression network based on an auto-encoder structure; according to a rate-distortion error calculation unit, alternately training a generative network; according to a target compression rate, calculating a mask threshold; based on a feature map channel redundancy index, calculating a mask; and performing lossless compression and decoding on the mask and the feature map. According to the invention, only a single model is trained, but compression results with different bit rates can be generated, and on a limit compression rate below 0.1 bpp.

  • Patent number: 11133669
    Abstract: A limiter having a more ideal limiting function, a short response time, and an adjustable limiting threshold. In one embodiment, a self-activating limiter stack is coupled between circuit ground and a signal line between a source and a receiver. The limiter stack limits the power from the source when the voltage on the signal line exceeds the breakdown voltage of the limiter stack. The threshold of the limiter stack is controlled in part by a first control voltage applied to a control input. A rectifying power detector circuit connected between a node on the signal line and the control input of the limiter stack provides a second control voltage as a function of the signal power at the node. The combined first and second control voltages are applied to the control input to modulate the ON resistance of the limiter stack, thereby limiting the leakage power reaching the protected receiver.

  • Patent number: 10680590
    Abstract: A fast response time, self-activating, adjustable threshold limiter including a limiting element LE, a first coupling element CE1 electrically connected from a signal node of LE to a control input of LE, and a second coupling element CE2 electrically connected from the control input of LE to a nominal node of LE. An initial bias (control) voltage is also supplied to the control input of LE to dynamically control the limiting threshold for the limiter. Embodiments include usage of self-activating adjustable power limiters in combination with series switch components in a switch circuit in lieu of conventional shunt switches.

  • Patent number: 10637526
    Abstract: An RF switching device having distributed shunt switches distributed along transmission lines to improve RF bandwidth as well as the signal isolation of the device. The shunt switches may be physically positioned on both sides of the transmission lines to keep an integrated circuit (IC) design essentially symmetrical so as to provide predictable and reliable operational characteristics. Some embodiments include stacked FET shunt switches and series switches to tolerate high voltages. In some embodiments, the gate resistor for each FET shunt switch is divided into two or more portions.

  • Publication number: 20180097539
    Abstract: A broadband power limiter having a distributed architecture of multiple segments of self-actuating, adjustable power limiters, where the limiter segments are separated from each other along a signal path by intermediate matching inductors. The intermediate matching inductors are chosen to form, in combination with the capacitances of the limiter segments, an impedance matched, low-loss, broadband transmission line. Optionally, limiter segments may be configured with different sizes and stack depths in a “tapered” architecture, such that different limiter segments have different power limiting response times and power handling capabilities. As each limiter segment initiates its power limiting action, power is reflected back toward the signal line, helping to trigger the power limiting action of the remaining limiter segments.
