    • A compact model of MOSFET mismatch for circuit design 

      Montoro, Carlos Galup; Schneider, Marcio Cherem; Klimach, Hamilton Duarte; Arnaud, Alfredo (2005) [Artigo de periódico]
      This paper presents a compact model for MOS transistor mismatch. The mismatch model uses the carrier number fluctuation theory to account for the effects of local doping fluctuations along with an accurate and compact dc ...

    • Dynamic and static calibration of ultra-low-voltage, digital-based operational transconductance amplifiers 

      Toledo, Pedro Filipe Leite Correia de; Crovetti, Paolo Stefano; Klimach, Hamilton Duarte; Bampi, Sergio (2020) [Artigo de periódico]
      The calibration of the effects of process variations and device mismatch in Ultra Low Voltage (ULV) Digital-Based Operational Transconductance Amplifiers (DB-OTAs) is addressed in this paper. For this purpose, two dynamic ...

    • Low temperature sensitivity CMOS transconductor based on GZTC MOSFET condition 

      Toledo, Pedro Filipe Leite Correia de; Klimach, Hamilton Duarte; Cordova, David Javier; Bampi, Sergio; Fabris, Eric Ericson (2016) [Artigo de periódico]
      Complementary Metal Oxide Semiconductor (CMOS) Transconductors, or Gm cells, are key building blocks to implement a large variety of analog circuits such as adjustable filters, multipliers, controlled oscillators and ...

    • Low-voltage, low-area, nW-power CMOS digital-based biosignal amplifier 

      Crovetti, Paolo Stefano; Klimach, Hamilton Duarte; Musolino, Francesco; Bampi, Sergio (2022) [Artigo de periódico]
      This paper presents the operation principle and the silicon characterization of a power efficient ultra-low voltage and ultra-low area fully-differential, digital-based Operational Transconductance Amplifier (OTA), suitable ...

    • MOSFET mismatch modeling : a new approach 

      Klimach, Hamilton Duarte; Arnaud, Alfredo; Montoro, Carlos Galup; Schneider, Marcio Cherem (2006) [Artigo de periódico]

    • MOSFET ZTC condition analysis for a self-biased current reference design 

      Toledo, Pedro Filipe Leite Correia de; Klimach, Hamilton Duarte; Cordova Vivas, David Javier; Bampi, Sergio; Fabris, Eric Ericson (2015) [Artigo de periódico]
      In this paper a self-biased current reference based on Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) Zero Temperature Coefficient (ZTC) condition is proposed. It can be imple mented in any Complementary ...
