Low-voltage 0.81mW, 1-32 CMOS VGA with 5% bandwidth variations and -38dB DC rejection
López Martín, Antonio
; Rico-Aniles, Héctor Daniel; Ramírez-Angulo, Jaime; Rocha-Pérez, José Miguel; González Carvajal, Ramón (IEEE, 2020)
Artículo / Artikulua 
A CMOS low-voltage amplifier with approximately constant bandwidth and DC rejection is introduced. The design is based on the cascade of a wide linear input range OTA, an op-amp and a servo-loop with extremely large time ... -
Power efficient simple technique to convert a reset-and-hold into a true-sample-and-hold using an auxiliary output stage
Rico-Aniles, Héctor Daniel; Ramírez-Angulo, Jaime; López Martín, Antonio ; González Carvajal, Ramón; Rocha-Pérez, José Miguel; Garde Luque, María Pilar (IEEE, 2020)
Artículo / Artikulua
A technique to implement true-sample-and-hold circuits that hold the output for almost the entire clock cycle without resetting to zero is introduced, alleviating the slew rate requirement on the op-amp. It is based on a ... -
Pseudo-three-stage Miller op-amp with enhanced small-signal and large-signal performance
Paul, Anindita; Ramírez-Angulo, Jaime; López Martín, Antonio ; González Carvajal, Ramón; Rocha-Pérez, José Miguel (IEEE, 2019)
Artículo / Artikulua
A simple technique to implement highly power efficient class AB-AB Miller op-amps is presented in this paper. It uses a composite input stage with resistive local common mode feedback that provides class AB operation to ...
