Continuous Time Extraction of a Nonstationary Signal with Illustrations in Continuous Low-pass and Band-pass Filtering
This paper sets out the theoretical foundations for continuous-time signal extraction in econometrics. Continuous-time modeling gives an effective strategy for treating stock and flow data, irregularly spaced data, and changing frequency of observation. We rigorously derive the optimal continuous-lag filter when the signal component is nonstationary, and provide several illustrations, including...
متن کاملA CMOS/SOI Continuous-Time Low-Pass gm-C Filter
This paper describes a preliminary comparative analysis between continuous-time gm-C filters based on a specific transcondutor but designed according to CMOS/bulk (conventional) and CMOS/SOI fabrication processes. A compensation technique to minimize the phase-error (lead-phase) of the basic integrator owing to the relatively high output-conductance of the adopted transconductor is examined. Su...
متن کاملA Continuous-Time Band-Pass Σ∆ Modulator Implemented in 0.35u BiCMOS using Transmission Lines
This work presents experimental results of a 6 order band-pass continuous-time sigma-delta modulator that uses transmission lines as resonators. It has been implemented in 0.35u SiGe BiCMOS technology. The modulator tolerates two clock cycles of excess loop delay and has similar clock jitter sensitivity than that of an equivalent switched capacitor solution. The ADC operates at a sampling rate ...

متن کاملPerformance Comparison of Continuous-Time IFLF and LF Low-Pass All-Pole OTA-C Filters
This paper presents the performance comparison of two typical multiple loop feedback all-pole operational transconductance amplifier-capacitor (OTA-C) filters: Inverse-follow-the-leader-feedback (IFLF) and Leapfrog (LF) filters. Two fourth-order structures are analysed and compared in terms of sensitivity, maximum input signal, noise, and OTA nonideality effects on magnitude response. Simulatio...
