Abstract:

An analysis of modern automated integrated analog circuits design methods and their use in integrated filter design is done. Current modern analog circuits automated tools are based on optimization algorithms and/or new circuit generation methods. Most automated integrated filter design methods are only suited to gmC and switched current filter topologies. Here, an algorithm for an active RC integrated filter design is proposed, that can be used in automated filter designs. The algorithm is tested by designing an integrated active RC filter in a 65 nm CMOS technology. Atlikta naujausių integrinių analoginių grandynų automatizuotojo projektavimo metodų ir jų taikymo projektuojant integrinius filtrus analizė. Modernios analoginių grandynų automatizavimo priemonės yra grindžiamos esamos topologijos optimizacijos algoritmais ir/arba naujų elektroninių principinių schemų generavimo būdais. Didžioji dauguma literatūroje aprašytų automatizuotojo integrinių filtrų projektavimo metodų yra skirti tik gm-C arba perjungiamos srovės/talpos topologijos filtrams. Darbe siūlomas naujas integrinių aktyviųjų RC filtrų projektavimo algoritmas, įvertinantis integrinių technologijų elementų nuokrypius. Jis patikrintas suprojektavus integrinį aktyvųjį RC filtrą taikant 65 nm KMOP technologiją ir Cadence programinį paketą.

Abstract:

Design methodology of a voltage-mode programmable biquadratic filter using minimum components is proposed in this paper. Multifunction second-order filter has been implemented using two first-order filter sections. The proposed biquadratic filter has been realized with operational transconductance amplifier (OTA). Cut-off frequency and [Formula: see text]-factor of the biquadratic are controlled by the transconductance of the OTAs. The proposed design technique keeps all the sensitivities to lower values. The biquadratic filter operates at high frequency. The proposed structure is transformed into a third-order multifunction filter by adding minimum component, a single capacitor. Design of higher order filter using the proposed second-order function also has been investigated. The proposed synthesis is validated with SPICE simulation in 0.13[Formula: see text][Formula: see text]m technology. Total harmonic distortion, output noise, corner simulations, Monte Carlo analysis due to the circuit parameter and process parameter variation have been studied.

Abstract:

Systems such as Gm-C filters are ideally designed to exhibit linear characteristics. However, their components – especially transconductors – are intrinsically nonlinear. Although there exist many approaches that aim at reducing nonlinear effects while dealing with practical design problems, nonlinear distortion cannot be canceled out completely. Thus, it is important to estimate a degradation of filter performance caused by nonlinearities. In this paper we propose a simple and general method to perform a transient analysis of any Gm-C filter structure based on a matrix description and macro-modeling of transconductors. An analytical description of general Gm-C filters with nonlinear transconductors is introduced. A differential system that determines dynamics of a general structure of Gm-C filter is formulated. This allows us to carry out an effective and fast transient analysis of any Gm-C filter using standard numerical methods. The approach can be applied to investigate any non-linear effects in filters. The noise analysis of Gm-C filters in general setting is also presented. The accuracy of the proposed methods is confirmed by comparison with SPICE simulation. Example of application for performance optimization of 4th order Chebyshev filter is given.

Abstract:

This paper describes a new single-input multiple-output (SIMO) mixed-mode universal biquad [Formula: see text]–[Formula: see text] filter. It can realize all kinds of filter responses including high-pass, band-pass, low-pass, band-stop and all-pass filters, simultaneously. Moreover, in this structure, all of these filters in all states of voltage mode, current mode, transresistance mode and transconductance mode are achieved by the same topology without any convertor. The proposed filter employs three operational transconductance amplifiers (OTAs) with four inputs and one output, three fully differential OTAs and two grounded capacitors. In other words, this filter is composed of six [Formula: see text] blocks and two grounded capacitors. The grounded capacitors are suitable for integrated circuit implementation. In order to reduce the power consumption, the OTAs are biased in subthreshold region. In addition, sensitivity analysis is included to show the low active and passive sensitivity performances of the filter. This filter is designed and simulated in HSPICE with 0.18[Formula: see text][Formula: see text]m model CMOS technology parameters. The simulation results show that the filter consumes only 75[Formula: see text][Formula: see text]W and operates at 1.5[Formula: see text]MHz with [Formula: see text]0.5[Formula: see text]V supply voltages and capacitors [Formula: see text][Formula: see text]pF.
