AMGIE-A synthesis environment for CMOS analog integrated circuits

High-Frequency Oscillator Design for Integrated Transceivers

“…Furthermore, the interval can be open or closed or be a single value. In other words it can be an inequality constraint or a equality constraint, respectively [60]. Examples are the power dissipation should be lower than 100 mW, the power supply voltage is 3 V ± 10%, and the tuning range should start at 1 MHz and extend to at least 1 GHz.…”

Design of Analog Integrated Circuits using Simulated Annealing/Quenching with Crossovers and Particle Swarm Optimization

“…This tool models the circuit in a set of analytic expressions which can be used by the optimization algorithm to fast evaluate each solution. Later, these tools were integrated into a synthesis environment called AMGIE [6] that covers the complete analog design flow, from specification to layout generation.…”

“…These approaches tried to capture the design knowledge required to perform some circuit implementation and implement it in algorithms. Optimization-based approaches started to be made in the late 1980's and are still an active area of research [6], [29], [27]. These approaches provide tools with greater flexibility and smaller overhead in comparison with knowledge-based approaches.…”

Analog circuits optimization based on evolutionary computation techniques

“…Analog design problem is typically an over constrained problem with many degrees of freedom and many performance requirements and it is still characterized by the lack of a unique and structured design flow definition. The majority of the applied techniques and tools used to solve the analog problem, such as DELIGHT.SPICE [1], ANACONDA [2], AMGIE [3], and APE [4], among many others [5], are based on powerful numerical optimization engines (e.g. evolutionary algorithms, geometric programming,) conjugated with evaluation engines (e.g.…”
