A 6th order low-pass 1.6 to 3.2GHz gm-C filter for fiber optic adaptive EDC receivers cascades three Bi-Quads permitting reduction of group delay variation down to 10ps. Cut-off frequency is tuned by switching CMOS varactors polarity. THD is below -40dB at 0.9Vpp-diff output. CTF is implemented in a 0.18 m SiGe process, it occupies 0.17mm and consumes 0.3W from 3.3V supply. Index Terms — Contin...

this paper presents a new design for a microstrip dual-band band-pass microstrip filter (bpf) with suitable isolation between two passbands. in this design, a basic structure is used to achieve a desirable frequency characteristic in the passband. in this regard, defected ground structure (dgs) is implemented to reach optimum parameters of the filter such as bandwidth, return loss, insertion lo...

In this paper, UWB technology operating in broad frequency range of 3.1-10.6 GHz has shown great achievement for highspeed wireless communications. to satisfy the UWB system requirements, a band pass filter with a broad pass band width, low insertion loss, and high stop-band suppression. UWB band-pass filter (BPF) with wireless local area network (WLAN) notch at 5.8 GHz and 3-dB fractional band...

A novel lOOMHz CMOS G,-C seventh-order 0.05" equiripple linear phase low-pass multiple loop feedback (MLF) filter based on the Leapfrog (LF) topology is presented. The filter is implemented using a fully-differential linear, high performance operational transconductance amplifier (OTA) based on crosscoupled pairs. PSpice simulations in a standard TSMC 0.25pm CMOS process and with a single 5V po...

Bertram, Richard, Michelle I. Arnot, and Gerald W. Zamponi. Role for G protein G isoform specificity in synaptic signal processing: A computational study. J Neurophysiol 87: 2612–2623, 2002; 10.1152/jn.00667.2001. Computational modeling is used to investigate the functional impact of G protein–mediated presynaptic autoinhibition on synaptic filtering properties. It is demonstrated that this for...
