Gong, J. (author)Quantum computers have gained widespread interest from both industry and academia in the last decade as they are very promising for solving problems intractable by classical computers. However, there is a limited number of qubits in current quantum processors, which impedes the practical applications of a quantum computer. To increase the number...doctoral thesis 2023

Pan, S. (author), An, Xiaomeng (author), Yu, Zheru (author), Jiang, H. (author), Makinwa, K.A.A. (author)This article presents the design and implementation of a compact CMOS RC frequency reference. It consists of a frequency-locked loop (FLL) that locks the period of a voltage-controlled oscillator (VCO) to the time an RC network takes to charge to a reference voltage. Conventionally, an RC time constant with a near-zero temperature coefficient...journal article 2023

Gong, J. (author), Charbon-Iwasaki-Charbon, E. (author), Sebastiano, F. (author), Babaie, M. (author)This article presents a low-jitter and low-spur charge-sampling phase-locked loop (CSPLL). A charge-domain sub-sampling phase detector is introduced to achieve a high phase-detection gain and to reduce the PLL in-band phase noise. Even without employing any power-hungry isolation buffers, the proposed phase detector dramatically suppresses...journal article 2022

Barzgari, Mohammad (author), Ghafari, A. (author), Meghdadi, Masoud (author), Medi, Ali (author)This article presents the theory and implementation of a quadrature and differential RF front-end receiver. Combining balun, low-noise amplifier (LNA), mixer, and oscillator in a single stage, the proposed circuit, named the Blixator, is well suited for low-power applications. The baseband's transimpedance amplifier (TIA) also shares part of...journal article 2022

(author)In this paper, we propose a new scheme to directly power a 4.9-5.6GHz LC oscillator from a recursive switched-capacitor DC-DC converter. A finite-state machine is integrated to automatically adjust the conversion ratio and switching frequency of the converter such that its DC output voltage is within ±5% of the desired 1V across input voltage...journal article 2020

A Supply Pushing Reduction Technique for LC Oscillators Based on Ripple Replication and CancellationChen, Y. (author), Liu, Yao-Hong (author), Zong, Z. (author), Dijkhuis, Johan (author), Dolmans, Guido (author), Staszewski, R.B. (author), Babaie, M. (author)In this paper, we propose a method to suppress supply pushing of an LC oscillator such that it may directly operate from a switched-mode dc-dc converter generating fairly large ripples. A ripple replication block (RRB) generates an amplified ripple replica at the gate terminal of the tail current source to stabilize the oscillator's tail...journal article 2019

Angevare, J. (author), Makinwa, K.A.A. (author)This paper describes a compact resistor-based temperature sensor that has been realized in a 180-nm CMOS process. It occupies only 6800 μ m<sup>2</sup>, thanks to the use of a highly digital voltage-controlled oscillator (VCO)-based phase-domain sigma-delta modulator, whose loop filter consists of a compact digital counter. Despite its small...journal article 2019

Sonmez, U. (author), Sebastiano, F. (author), Makinwa, K.A.A. (author)An array of temperature sensors based on the thermal diffusivity (TD) of bulk silicon has been realized in a standard 40-nm CMOS process. In each TD sensor, a highly digital voltage-controlled oscillator-based Σ Δ ADC digitizes the temperature-dependent phase shift of an electrothermal filter (ETF). A phase calibration scheme is used to...journal article 2017

Shen, J. (author)A voltage controlled oscillator (VCO) is an integral part of a phase lock loop (PLL) which by itself is the core of the frequency reference in a radar system. The generation of the in-phase and quadratue signals is crucial for many radar applications. A 60GHz quadrature voltage controlled oscillator (QVCO) is presented in this thesis. The design...master thesis 2010
