A Low Distortion Sine-Wave Generator based on a Resistive DACs

This thesis proposes a novel low distortion, on-chip sine-wave generator. A low distortion input is required in many test and measurement setups for analog and mixed-signal systems, where the input signal should have less distortion than that contributed by the device under test (DUT). For conventional oscillators, there is a compromise between...

Ultra Linear Low-loss Varactors & Circuits for Adaptive RF Systems

With the evolution of wireless communication, varactors can play an important role in enabling adaptive transceivers as well as phase-diversity systems. This thesis presents various varactor diode-based circuit topologies that facilitate RF adaptivity. The proposed varactor configurations can act as variable capacitors with high tuning range,...
