US11888775B2	Time and frequency tracking reference signals in new radio In NR, a slot structure of a UE may be dynamic due the number of symbols of PDCCH and whether the slot has UL data, among other considerations. Additionally, to support multi-TRP/multi-panel/multi-BWP operation, a UE may be configured with multiple TRSs, and when a UE needs to receive multiple TRSs in the same slot, efficient signaling of the TRSs is important because of the high overhead involved.

US11888468B2	Tuning capacitance to enhance FET stack voltage withstand An RF switch to controllably withstand an applied RF voltage Vsw, or a method of fabricating such a switch, which includes a string of series-connected constituent FETs with a node of the string between each pair of adjacent FETs. The method includes controlling capacitances between different nodes of the string to effectively tune the string capacitively, which will reduce the variance in the RF switch voltage distributed across each constituent FET, thereby enhancing switch breakdown voltage. Capacitances are controlled, for example, by disposing capacitive features between nodes of the string, and/or by varying design parameters of different constituent FETs. For each node, a sum of products of each significant capacitor by a proportion of Vsw appearing across it may be controlled to approximately zero.
US11888467B2	Temperature compensation of analog CMOS physically unclonable function for yield enhancement An apparatus includes a current-based temperature compensation circuit having a reference buffer, a biasing current mirror, and a controller. The reference buffer is configured to receive a biasing reference voltage at a voltage input terminal and replicate the biasing reference voltage to first and second buffer terminals. At least one of the first and second buffer terminals is configured to be electrically connected to at least one gate terminal of an analog complementary metal oxide semiconductor (CMOS) physically unclonable function (PUF) cell. The biasing current mirror is configured to receive a reference current at a current input terminal and replicate the reference current to the first buffer terminal. The controller is configured to compensate an output of the CMOS PUF cell for temperature variation based on a weighted sum of a bandgap current, a current proportional to absolute temperature, and a current complementary to absolute temperature.
