Patent number: 11411566Abstract: In described examples, a method of operating a charge pump includes a first control signal deactivating a first transistor, and the first control signal's logical complement activating a second transistor to reset the first transistor's DC bias voltage. The first control signal's logical complement deactivates the second transistor, and the first control signal provides a bias voltage to the first transistor to activate it, causing current to be transmitted from an input voltage to an output terminal. A second control signal deactivates a third transistor, and the second control signal's logical complement activates a fourth transistor to reset the second transistor's DC bias voltage. The second control signal's logical complement deactivates the fourth transistor, and the second control signal provides a bias voltage to the third transistor to activate it, causing current to be transmitted from the output terminal to a ground.Type: GrantFiled: August 9, 2021Date of Patent: August 9, 2022Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Salvatore Luciano Finocchiaro, Tolga Dine, Gerd Schuppener, Siraj Akhtar, Swaminathan Sankaran, Baher Haroun

Patent number: 11405042Abstract: In described examples, a method of operating a transceiver with a transmitter and a receiver includes generating a frequency reference. In the transmitter: A phase locked loop (PLL) generates a first voltage controlled oscillator (VCO) control voltage responsive to the frequency reference. A VCO in the transmitter generates a transmitter VCO signal responsive to the first VCO control voltage, and the PLL is locked to the transmitter VCO signal. In the receiver: A signal is received. A receiver VCO generates a receiver VCO signal responsive to the first or a second VCO control voltage. The receiver VCO signal is multiplied by the received signal to generate an I component, and by the received signal phase shifted by 90° to generate a Q component. The second VCO control signal is generated responsive to the I component and the Q component.Type: GrantFiled: December 31, 2019Date of Patent: August 2, 2022Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Salvatore Luciano Finocchiaro, Timothy Schmidl, Tolga Dinc, Gerd Schuppener, Siraj Akhtar, Swaminathan Sankaran, Baher Haroun

Patent number: 10979277Abstract: In described examples, a method of operating a transmitter includes generating a frequency reference signal having a reference frequency and outputting the frequency reference to a phase locked loop (PLL) that includes a voltage controlled oscillator (VCO). The VCO output is locked to the frequency reference signal to form a carrier signal. The transmitter receives an I input signal, a Q input signal, and a direct current (DC) leaky carrier signal. Either the I input signal or the Q input signal is added to the leaky carrier signal. The carrier signal is modulated with the resulting two signals using an I-Q mixer to generate a modulated signal that includes an unmodulated carrier signal component. The modulated signal is then transmitted.Type: GrantFiled: December 31, 2019Date of Patent: April 13, 2021Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Timothy Mark Schmidl, Swaminathan Sankaran, Gerd Schuppener, Salvatore Luciano Finocchiaro, Siraj Akhtar, Tolga Dinc, Anand Ganesh Dabak, Baher Haroun
