In this paper we highlight drawbacks of the use of a priori optimized current conveyor (CC) as basic building block of active circuits. We use the optimization based technique to act directly on the ports of the current conveyors encompassing the overall active circuits in order to make them behave as 'ideal' as possible by minimizing their parasitic effects, offsets, etc. Three active circuits are presented, namely two active filters and a simulated inductance. Obtained results are given and compared to the ideal ones and also to those reached using an 'optimized' building block.

Analog circuits operating in the weak inversion region of the transistors are being used as an ideal option for low power CMOS design. In this paper, we present three optimized CMOS second generation current conveyors (CClIs) operating in the weak inversion region. Simulation-based approach is adopted to assist an optimization algorithm that is also presented in this brief. HSPICE simulations are presented to show good reached performances.

“…The second one, i.e. the simulationbased approach, is based on the use of a circuit simulator such as SPICE, which evaluates the circuit's performance(s) and constraints, as well [12][13][14]. The key of this transition is the feasibility to include SPICE like simulators within the loop of any circuit design optimization problem.…”

Abstract. The continuing size reduction of electronic devices imposes design challenges to optimize the performances of modern electronic systems, such as: wireless services, telecom and mobile computing. Fortunately, those design challenges can be overcome thanks to the development of Electronic Design Automation (EDA) tools. In the analog, mixed signal and radio-frequency (AMS/RF) domains, circuit optimization tools have demonstrated their usefulness in addressing design problems taking into account downscaling technological aspects. Recent advances in EDA have shown that the simulationbased sizing technique is a very interesting solution to the 'complex' modelling task in the circuit design optimization problem. In this paper we propose a multi-objective simulation-based optimization tool. A CMOS LC-VCO circuit is presented to show the viability of this tool. The tool is used to generate the Pareto front linking two conflicting objectives, namely the VCO Phase Noise and Power Consumption. The accuracy of the results is checked against HSPICE/RF simulations.
