چکیده

A broadband, Mach-Zehnder-interferometer based silicon optical modulator is demonstrated, with an electrical bandwidth of 26 GHz and V(pi)L of 4 V.cm. The design of this modulator does not require epitaxial overgrowth and is therefore simpler to fabricate than previous devices with similar performance.

First Order Sigma-delta Modulator with Low-power Consumption Implemented in Ams 0.35 Μm Cmos Technology

Abstract This paper presents a design of a switched-capacitor discrete time 1st order Delta-Sigma modulator used for a resolution of 8 bits Sigma-Delta analog to digital converter. For lower power consumption, the use of operational transconductance amplifier is necessary in order to provide wide output voltage swing and moderate DC gain. Simulation results showed that with 0.35um CMOS technolo...

A Hysteretic Two-phase Supply Modulator for Envelope Tracking RF Power Amplifiers

In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...
