Publication number: 20230223971Abstract: A radio-frequency modulator apparatus comprises a baseband stage, a mixer stage and a radio-frequency stage. The baseband stage comprises: an input line for receiving an input current representative of a baseband input signal, a baseband transistor that passes some or all of the input current between a first and a second terminal thereof, an electrical connection between the input line and a control terminal of the baseband transistor, and an output line connected to said control terminal. The mixer stage receives a signal from the baseband stage and mixes it with a radio-frequency local-oscillator signal to generate a radio-frequency mixed signal. The radio-frequency stage receives the radio-frequency mixed signal, applies the radio-frequency mixed signal to a control terminal of a radio-frequency transistor causing it to pass a radio-frequency output current between a first and a second terminal thereof, and outputs the radio-frequency output current as an output signal.Type: ApplicationFiled: May 13, 2021Publication date: July 13, 2023Applicant: Nordic Semiconductor ASAInventors: Marko PESSA, Sami KARVONEN

Publication number: 20220368286Abstract: An RF amplifier comprises a first ‘transconductance’ transistor (NCS) arranged to receive an RF input voltage (RFIN) at its gate terminal. A second ‘cascode’ transistor (NCG) has its source terminal connected to the drain terminal of the first transistor (NCS) at a node (MID). A feedback circuit portion is configured to measure a node voltage at the node (MID), to determine an average of the node voltage, to compare said average node voltage to a predetermined reference voltage (VBCG), and to generate a control voltage (CGGATE) dependent on the difference between the average node voltage and the predetermined reference voltage (VBCG). The feedback circuit portion applies the control voltage (CGGATE) to the gate terminal of the second transistor (NCG).Type: ApplicationFiled: May 16, 2022Publication date: November 17, 2022Applicant: Nordic Semiconductor ASAInventors: Marko Pessa, David Zapata

Patent number: 10992132Abstract: A power control system provides multiple supply voltages that are guaranteed not to violate boundary conditions regardless of the timing of voltage change commands. A first voltage (Vlogic in the embodiments described herein) is controlled conventionally, and a second voltage (Vmemory) is either selected or generated by adding a selected offset to the first voltage. Both the size of the offset, and the absolute value of the second voltage, are constrained at all times, by constraint values specific to the current voltage zone. The invention ensures a smooth transition between different voltage operating points, and ensures that the trajectory of change between specified operating points remains within predefined boundaries.Type: GrantFiled: July 18, 2019Date of Patent: April 27, 2021Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Joni Jäntti, Cecilia Andersson, Bengt Edholm, Masao Naruse, Harri Nissi, Marko Pessa, Mikko Pulkkinen

Patent number: 10678288Abstract: A power management circuit generates a reference voltage and distributes it to a plurality of independently-enabled regulator voltage reference circuits, each of which generates a predetermined voltage for a voltage regulator. Separate enable signals and enable pre-charge signals are distributed to each regulator voltage reference circuit. As a regulator voltage reference circuit is enabled via its associated enable signal, an enable pre-charge signal is also asserted for an initial duration. Each regulator voltage reference circuit includes a voltage setting circuit and a first current limiting transistor in series and operative to interrupt current to the voltage setting circuit when the regulator voltage reference circuit is disabled. A second current limiting transistor is configurably configured as a current mirror with the first current limiting transistor, and a pre-charge bias current from a current source passes through the second transistor.Type: GrantFiled: August 30, 2019Date of Patent: June 9, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mikko Lintonen, Marko Pessa
