Patent number: 10140229Abstract: Triggered remote function calls can be used in master-slave systems to trigger slave-side software functions pre-loaded by a master into slave MCU memory, with associated parameters pre-loaded into a slave function interface memory. A master issues trigger-function signals (such as rising/falling edges or signal levels) over a trigger-function signal line. The slave includes a trigger conditioning block that in response issues a trigger-function request to the slave MCU, which calls/executes the associated software function, including accessing the associated trigger-function parameters from function interface memory. A slave can include a hardware function block with functionality configurable by a pre-loaded software configuration function (with associated parameters). A master can include a hardware function block configured to issue trigger-function signals.Type: GrantFiled: August 10, 2015Date of Patent: November 27, 2018Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Xiaoxi Zhang, Nikolaus Klemmer, Hunsoo Choo

Patent number: 9998169Abstract: A phase rotator corrects the IQ imbalance in a wireless transceiver. The phase rotator is a part of a compensation system that detects and separates reception impairment images from transmission impairment images. The disclosed phase rotator introduces a phase shift between the transmission channel and the reception channel without perturbing the phase mismatch and the gain mismatch in the reception path. The phase rotator includes a first local oscillation (LO) circuit that generates a first LO signal at a first carrier frequency and a second LO circuit that generates a second LO signal at a second carrier frequency that deviates from the first carrier frequency for a phase rotation period. The phase rotation period is sufficiently long such that the frequency deviation can introduce a prescribed phase shift between the first LO signal and the second LO signal.Type: GrantFiled: March 22, 2017Date of Patent: June 12, 2018Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Charles Kasimer Sestok, IV, Hunsoo Choo, Nikolaus Klemmer, Xiaoxi Zhang
