Publication number: 20240421788Abstract: Disclosed herein are signal amplifiers that include a plurality of switchable amplifier architectures so that particular gain modes can use dedicated amplifier architectures to provide desired characteristics for those gain modes, such as low noise figure or high linearity. The disclosed signal amplifier architectures provide tailored impedances using a degeneration block or matrix without using switches in the degeneration switching block. The disclosed signal amplifier architectures provide a plurality of gain modes where different gain modes use different paths through the amplifier architecture. Switches that are used to select the path through the amplifier architecture also provide targeted impedances in a degeneration block or matrix. The switches that select the gain path are provided in the amplifier architecture and are thus not needed or used in the degeneration block, thereby reducing the size of the package for the amplifier architecture.Type: ApplicationFiled: June 24, 2024Publication date: December 19, 2024Inventors: Junhyung Lee, Johannes Jacobus Emile Maria Hageraats, Yan Yan, Bumkyum Kim, Aravind Kumar Padyana, Joshua Haeseok Cho, Rimal Deep Singh, Bipul Agarwal

Patent number: 11329621Abstract: Described herein are variable gain amplifiers and multiplexers that embed programmable attenuators into switchable paths to provide variable gain for individual amplifier inputs. The variable gain for an individual input is provided using an amplification stage that is common for each input of the amplifier. A variable attenuation is provided for individual inputs through a combination of a band selection switch and an attenuation selection branch. Individual inputs can be configured to bypass the variable attenuation in a high gain mode.Type: GrantFiled: October 6, 2020Date of Patent: May 10, 2022Assignee: SKYWORKS SOLUTIONS, INC.Inventors: Junhyung Lee, Rimal Deep Singh, Johannes Jacobus Emile Maria Hageraats, Joshua Haeseok Cho, Bipul Agarwal, Aravind Kumar Padyana

Patent number: 10348262Abstract: Described herein are variable gain amplifiers and multiplexers that embed programmable attenuators into switchable paths that allow signals in a high gain mode to bypass attenuation. This advantageously reduces or eliminates performance penalties in the high gain mode. The programmable attenuators can be configured to improve linearity of the amplification process through pre-LNA attenuation in targeted gain modes. In addition, described herein are variable gain amplifiers with embedded attenuators in a switching network. The attenuators can be embedded onto switches and can be configured to have little or no effect on a noise factor in a high gain mode because the switching network can provide an attenuation bypass in a high gain mode and an attenuation in other gain modes. The programmable attenuators can be embedded onto a multi-input LNA architecture.Type: GrantFiled: August 30, 2017Date of Patent: July 9, 2019Assignee: SKYWORKS SOLUTIONS, INC.Inventors: Junhyung Lee, Rimal Deep Singh, Johannes Jacobus Emile Maria Hageraats, Joshua Haeseok Cho, Bipul Agarwal, Aravind Kumar Padyana
