Journal ArticleDOI
Novel VCO Architecture Using Series Above-IC FBAR and Parallel LC Resonance
TL;DR: A quasi-monolithic voltage-tunable film bulk acoustic resonator (FBAR) enhanced oscillator for 2.1 GHz in 0.25-mum SiGe BiCMOS technology offers advantages in overcoming frequency tuning difficulties usually present when using high-Q resonators.
Journal ArticleDOI
Dual-Band LC VCO Architecture With a Fourth-Order Resonator
TL;DR: A dual-band LC voltage-controlled oscillator (VCO) architecture suitable for GSM/PCS/DCS applications is presented that utilizes a fourth-order resonance tank and avoids quality-factor-deteriorating switches.
Journal ArticleDOI
Theoretical Model of Ungrounded Inductance Realized With Two Gyrators
TL;DR: The discussed model gives a unified approach for theoretical analysis of gyrator LC filters with floating inductors, and separates the simulated inductance from the amplification, thus suggesting more flexible filter design.
Journal ArticleDOI
Design Considerations in Tapped-Inductor Fourth-Order Dual-Band VCO
TL;DR: A theoretical analysis of the constraints posed by a tapped inductor on a dual-band fourth-order voltage-controlled oscillator (VCO) is presented and guidelines for frequency band selection, tapped-inductor design, and VCO optimization are provided.
Journal ArticleDOI
Semi-symbolic analysis (SSA) for amplitude control design of series resonance low-voltage VCO
TL;DR: In this paper, the effect of an amplitude diode limiter on the oscillating conditions and frequency of oscillation of a 2.7 GHz series resonance LC-VCO, designed on Spectre-Cadence and implemented on 0.25 /spl mu/m BiCMOS process of Bell Labs, Lucent Microelectronics, is analyzed by semi-symbolic analysis.
