Circuit design

Circuit design

The Circuit design group of the IMS Laboratory relies on three teams (known as CAS, HSC and NSC) dedicated to analog, RF and digital circuit design. It forms a powerful complementary work force to provide fully integrated solutions to complex electronic systems. This team consists of 8 Professors, 11 Associate Professors, 15 PhD students, 1 IGE, 1 IR and 1 secretary.

Major activities and highlights

  • SASP (Sampled Analog Signal Processing) circuit in the receiving system and original solutions to the transmitter, ie the system Riemann pump and Walsh transmitter to generate one or more modulated signals over very wide bands
  • Development of an original radio demodulation principle called "MOOD" to reduce the power consumption by a factor of 10 compared to the commercially available solutions. This new receiver has also the advantage of being compatible with 2 types of the most common modulations in WSN: Frequency (FSK) and amplitude (OOK).
  • Realization of a 100 GB/s clock and data recovery in 130nm SiGe BiCMOS technology, STMicroelectronics.
  • Design of RF power amplifiers (PA) and mmW for LTE applications (collaboration ETS), WiGig (Cifre common lab ST / IMS), RADAR X-band / Ku-band UWB using CMOS technology, CMOS SOI, SiGe, GaN.
  • Development of PA linearization techniques such as Doherty, Cartesian loop feedback, Envelope Tracking ...
  • Passive Filter Design using BAW technology and active filters design using AsGa and GaN technology.
  • Characterization and modelling of analog to digital converters (ADC) and digital-to-analog converter (DAC)
  • Digital Improvement of analog and mixed circuit
  • New method to compensate mismatch errors in Time Interleaved ADC (TI-ADC)

M4C

Characterisation, measurement techniques The technologies studied, whether advanced or emerging, need to be characterised in order to extract their performance (extraction of figures of merit), as well as to extract model parameters. Several types of spike measurements can be performed. RF characterisation up to 500 GHz RF on-wafer measurements require the use of off-wafer and on-wafer calibration techniques adapted to frequency bands […]
