Bandwidth Tuning

This article presents a wideband reconfigurable integrated low-pass filter (LPF) for 5G NR compatible software-defined radio (SDR) solutions. The filter uses Active-RC topology to achieve high linearity performance. Its bandwidth can be tuned from 2.5 MHz to 200 MHz, which corresponds to a tuning ratio of 92.8. The order of the filter can be changed between the 2nd, 4th, or 6th order; it has built-in process, voltage, and temperature (PVT) compensation with a tuning range of ±42%; and power management features for optimization of the filter performance across its entire range of bandwidth tuning. Across its entire order, bandwidth, and power configuration range, the filter achieves in-band input-referred third-order intercept point (IIP3) between 32.7 dBm and 45.8 dBm, spurious free dynamic range (SFDR) between 63.6 dB and 79.5 dB, 1 dB compression point (P1dB) between 9.9 dBm and 14.1 dBm, total harmonic distortion (THD) between −85.6 dB and −64.5 dB, noise figure (NF) between 25.9 dB and 31.8 dB and power dissipation between 1.19 mW and 73.4 mW. The LPF was designed and verified using 65 nm CMOS process; it occupies a 0.429 mm2 area of silicon and uses a 1.2 V supply.

This paper presents different novel CMOS realizations for the differential difference operational floating amplifier (DDOFA). The DDOFA was first introduced in Ref. 1 and was used to realize different analog circuits like integrators, filters and variable gain amplifiers. New CMOS realizations for the DDOFA are introduced in this literature. Furthermore the DDOFA is modified to realize a fully differential current conveyor (FDCC). Novel CMOS realizations of the FDCC are presented. The FDCC is used to realize second-order band pass–low-pass filter. Performance comparisons between the different realizations of the DDOFA and FDCC are given in this literature. PSPICE simulations of the overall proposed circuits are given using 0.25 μm CMOS Technology from TMSC MOSIS model and dual supply voltages of ±1.5 V.

Anti-aliasing filter is widely used in the field of communication and the information collecting system. Generally, anti-aliasing filter is consisted with a low-pass filter, which possesses rapid roll-off rate. In order to ensure that there will be a very smooth amplitude frequency characteristic, the high order Butterworth low-pass filter is adopted to work as anti-aliasing filter. As we know, to design this kind of high order low-pass filter will involve large amount of manual calculation. In order to reduce the manual calculation job, which is meaningless and reduplicated, in this paper, a MATLAB scripts is proposed to establish a model of computer aided design for anti-aliasing filter. To use this MATLAB scripts, the value of parameter for the filter can be easily got according to the design specification.

Focusing on the amplifier performance evaluation demand, a novel evaluation strategy based onδ-support vector regression (δ-SVR) is proposed in this paper. Lower computer calculation demand is considered firstly. And this is dealt with by the superiority ofδ-SVR which can be significantly improved on the number of support vectors. Moreover, the function ofδ-SVR employs the modified RBF kernel function which is constructed from an original kernel by removing the last coordinate and adding the linear term with the last coordinate. Experiment adopted the typical circuit Sallen-Key low pass filter to prove the proposed evaluation strategy via the eight performance indexes. Simulation results reveal that the need of the number ofδ-SVR support vectors is the lowest among the other two methods LSSVR andε-SVR under obtaining nearly the same evaluation result. And this is also suitable for promotion computational speed.

Rocket Thrust

This research focuses on the electrical noise coming from the sensor: load cell which is being used in rocket thrust measurement system. The aim is to investigate the noise contained in the measurement data. Fast Fourier Transform (FFT) is used as an indicator for appropriate cut off frequency in filtering data. Low Pass Filter is used as the measurement of thrust for it produces steady-state signal and acceptable transient response. Results confirmed that there are significant differences for Signal Noise Ratio (SNR) value between filtered and unfiltered data. Data noise has an impact to the true value of the expected results that affects data interpretation. It is shown that the influence of noise on the measurement data has been successfully reduced by the method used.
