Un nouveau modulateur delta-sigma utilisant un quantificateur à diode résonante à effet tunnel (RTD) est proposé et son fonctionnement est étudié par des simulations HSPICE. Afin d'éliminer la dégradation du rapport signal sur bruit et distorsion (SINAD) causée par la mauvaise isolation d'un quantificateur à un étage (1SQ), un quantificateur à trois étages (3SQ), composé de trois quantificateurs RTD cascodés , est introduit. À une fréquence d'échantillonnage de 10 Gsps (échantillons par seconde) et une bande passante du signal de 40 MHz (taux de suréchantillonnage de 128), le modulateur démontre un SINAD de 56 dB, ce qui correspond au nombre effectif de bits de 9.3.

Abstract: A novel delta-sigma modulator that utilizes a resonant-tunneling diode (RTD) quantizer is proposed and its operation is investigated by HSPICE simulations. In order to eliminate the signal-to-noise-and-distortion ratio (SINAD) degradation caused from the poor isolation of a single-stage quantizer (1SQ), a three-stage quantizer (3SQ), which consists of three cascoded RTD quantizers, is introduced. At a sample rate of 10 Gsps (samples per a second) and a signal bandwidth of 40 MHz (oversampling ratio of 128), the modulator demonstrates a SINAD of 56 dB, which corresponds to the effective number of bits of 9.3.
