SUMMARY:

This work is an extension of previous studies and presents the research and development of a pulse width programmable gain integrating amplifier for chip systems. One of the main advantages of the proposed PGA architecture is that it uses few components and the number of gain values is independent of the circuit area. In addition, the architecture can be configured to operate with single-ended or differential signals.

 

Before starting the Integrated Circuit (IC) development, equations defining the uncertainties of the circuit were obtained and a discrete circuit was designed, simulated, and developed, which went through a series of experiments to validate the proposed architecture.

 

The implementation of the architecture in an IC aims to achieve higher operating frequencies, allowing its use in a wider range of applications. The integrated circuit was designed using the TSMC 0.18 µm CMOS technology, presenting an average power dissipation of 123.2 µW and occupying an area of approximately 0.065 mm2.

 

Transient simulations were performed with and without noise, DC, AC, PSS, PAC, Corner, and Monte Carlo, evaluating means, uncertainties, relative and absolute errors related to various parameters. This suggests that the circuit was carefully designed and tested, and the presented results provide a solid basis for the application of the proposed PGA in a wide range of analog conditioning applications.
