Accurate polynomial-regression based models are developed for power and frequency of the VCO. The goodness-of-fit of the models is evaluated using SSE, RMSE and R 2 . Using these models, we form a constrained optimization problem which is solved using genetic algorithm.

由于LC-tank的两端电压都是 VDD ，为了获得更大的调谐范围，我们需要用一个金属电容进行 ac couple，使得可变电容的两端电压不出现永远只有一端高的情况，同时， 利用大电阻进行隔离，电路图如下。

This paper presents a comprehensive review of tuning techniques of on-chip Terahertz VCO. Case studies are introduced for the tuning techniques of bias tuning, varactor tuning with enhanced negative resistance, inductive tuning and indirect varactor tuning.

Transceiver Case Studies – Philips GSM Transceiver q Dual conversion in both receive and transmit paths q Two LNAs are used to allow the use of two low-cost lossy image-reject filters

2023年3月1日 · A layout footprint test case was developed using two different tap points, at a certain distance from the VCO vehicle, for substrate signal injection, as to simulate and benchmark both single-tone and multi-tone substrate signal crosstalk scenarios.

Voltage-controlled oscillator (VCO)-based analogue-to-digital (A/D) conversion has recently attracted a lot of interest since it allows relatively easy implementation of multi-bit noise shaping A/D conversion. Both closed-loop as well as open …

Abstract—This paper investigates mixed-signal design for double-gate (DG) FinFET technology using a current-starved voltage controlled oscillator (VCO) as a case study. Design issues of the DG FinFET-based VCO is presented in a comparative perspective with a classical CMOS VCO.
