“…The PMOS transistors instead of NMOS transistors have been used in the varactor design because of its low flicker noise. To reduce the flicker (1/f) noise contributed by MOS switches, the device area can be increased as shown in (5). A larger area means a lower tuning range, so we need to adjust the area properly.…”

“…VCO may be realized with many configurations according to the applications and performance requirements. The available fundamental approaches are ring oscillator [1]- [3], inductance-capacitance (LC) oscillator [4], [5] tunable active inductor (TAI) based oscillator [6], [7], and relaxation oscillator [8]. Apart from the phase noise (PN); tuning range, power consumption, and output waveform are also necessary VCO specifications.…”

Voltage controlled oscillator (VCO) offers the radio frequency (RF) system designer a freedom to select the required frequency. Today's wireless communication system imposes a very stringent requirement in terms of phase noise generated in VCO. This study presents an inductive source degeneration technique to improve the phase noise performance of the inductance-capacitance (LC)-VCO. Double cross-coupled topology has been chosen for the proposed VCO. The post layout simulations with the parasitic resistance, inductance, capacitance (RLC) extracted view is carried out with united microelectronics corporations (UMC) 0.18 µm process by spectre simulator of cadence tools. The proposed VCO provides a phase noise of -124.3 dBc/Hz @ 1 MHz. The tuning range obtained is 19.87% with a centre frequency of 2.46 GHz which makes it suitable for industrial, scientific, and medical (ISM) band applications. It consumes a power of 2.10 mW. Also, a good figure of merit of -189 is achieved. The total layout area occupied is 477×545 µm 2 .

“…LC VCO as a widely used component in high-speed communication applications, and many studies have been conducted on the SETs of LC VCO in the cosmic radiation environment [8][9][10][11][12][13][14]. When a single particle hits a sensitive node in VCO, it can lead directly to frequency deviation and signal distortion of the VCO outputs and even a temporary stop of oscillation [2,15].…”

A Single-Event Transient Radiation Hardened Low-Dropout Regulator for LC Voltage-Controlled Oscillator

et al. 2022

A voltage-controlled oscillator (VCO) is an essential part of the clock circuitry in satellite communication systems. Low-dropout regulators (LDO) provide stable voltage supply to the VCO and inevitably bring in new radiation-sensitive nodes. In this paper, by conducting single-event transient (SET) sensitivity analysis of LDO in voltage-regulated VCO, we find the sensitive nodes of LDO in oscillation circuits located on the relevant transistors that determine the bias voltage of the tail transistor in the error amplifier (EA). To immunize SET, a symmetrical hardening method combining sensitive node splitting and resistive-decoupling is proposed for the sensitive nodes. This method achieves 80.8% analog single-event transient (ASET) mitigation. This study was conducted in 28-nm CMOS process.

“…The injection locked LC‐VCO has been designed to mitigate the SET effect in [18]. In [19], the theoretical analysis to capture the SET‐induced amplitude and phase variation in the LC‐VCO is proposed. The LC‐VCO for space application was simulated using a cryogenic transistor model in [20].…”

“…Since inductor capacitor-voltage controlled oscillator (LC-VCOs) has better phase noise performance over delay cell-based ring oscillators, SET tolerance of LC-VCO has been reported in several works [13][14][15][16][17][18][19][20]. In [13], a decoupling resistor is used in series with a bias transistor to minimise the SET effect in the LC VCO.…”

Single-event transients (SETs) due to heavy-ion (HI) strikes adversely affect the electronic circuits in the sub-100 nm regime in the radiation environment. This study proposes techniques to mitigate SETs in CMOS voltage-controlled oscillators (VCOs) without affecting the circuit specifications. A circuit asymmetry technique is used for faster recovery of the oscillator in the event of a single event transient (SET) caused by an ion hit. Also, a new SET tolerant inductor capacitor-voltage controlled oscillator (LC-VCO) topology is proposed for a radiation environment that shows reduced phase displacement, amplitude displacement, and recovery time. A comparison has been made with various LC-VCOs that have an inherent rad-hard capability which proves a significant improvement in SET sensitivity.
