Tcmos: low noise power supply technique for digital ics
González Jiménez, José Luis; Rubio Sola, Jose Antonio (1995-08)
Article
Accés obertMixed signal circuits have become an important trend in IC design. In these circuits, the effect of digital noise on the analogue part of the circuit is one of the most important performance constraints. The authors ... -
Temperature sensors to measure the central frequency and 3 dB bandwidth in mm W power amplifiers
Altet Sanahujes, Josep; Mateo Peña, Diego; Gómez Salinas, Dídac; González Jiménez, José Luis; Martineau, B.; Siligaris, Alexandre; Aragonès Cervera, Xavier (2014-04)
Article
Accés restringit per política de l'editorialThis letter introduces a novel on-chip measurement technique for the determination of the central frequency and 3 dB bandwidth of a 60 GHz power amplifier (PA) by performing low frequency temperature measurements. The ... -

Tesi
Accés obertEl ruido de conmutación generado por los circuitos digitales representa un problema importante que a menudolimita las prestaciones de los circuitos integradosdigitales y mixtos. éste ruido de conmutación estápresente en ... -
THERMAL OBSERVATION OF A MODULATED INPUT FOR A 2.5GHZ CMOS POWER AMPLIFIER Part 1: Feasibility study
Martin, Mikel; González Jiménez, José Luis (2011-03-02)
Report de recerca
Accés restringit per política de l'editorialIn this Project, the verification of the possibility of extraction of information of a modulated signal through no-invasive thermal measurements is done. The main objective is that using a non-invasive thermal technique, ... -
THERMAL OBSERVATION OF A MODULATED INPUT FOR A 2.5GHZ CMOS POWER AMPLIFIER Part 2: Temperature Sensor
Martín, Mikel; González Jiménez, José Luis (2011-04-25)
Report de recerca
Accés restringit per política de l'editorialThe temperature sensor used is based on the usual two bipolar transistors temperature sensor with some modifications to allow for external calibration (or “re-centering”). -
THERMAL OBSERVATION OF A MODULATED INPUT FOR A 2.5GHZ CMOS POWER AMPLIFIER Part 3: PA+Sensor layout integration and PVT analysis
Martín, Mikel; González Jiménez, José Luis (2011-05-16)
Report de recerca
Accés restringit per política de l'editorialThe objective is to detect the impact of PVT variations (Process, Voltage and Temperature variations) on the figures of merit of a device. -
VCO phase noise and sideband spurs due to substrate noise generated by on-chip digital circuits
Méndez Villegas, Miguel Ángel; Osorio Tamayo, Juan Felipe; Mateo Peña, Diego; Aragonès Cervera, Xavier; González Jiménez, José Luis (Institute of Electrical and Electronics Engineers (IEEE), 2006)
Text en actes de congrés
Accés obertThis paper presents the effects of noise generated by realistic digital circuits on RF voltage controlled oscillators (VCO) integrated in the same silicon die. The digital noise is coupled through the common substrate and ...
