“…To obtain a reliable exploitation of these signals, an important amplification is necessary. However, this amplification should only concern the useful signal but it often carries alongside two other spurious signals: a voltage called "common mode" which can arise from the current supply or from the ground and an interference voltage which is generated by the amplifier itself or arises from surrounding electromagnetic inductions [10]. The useful signal being very low, the problem is to design an amplifier which discriminates it from the noise.…”

Background: There is a huge gap in the audiological care in Africa by comparison with Western countries. Its main reason is the prohibitive cost of the medical devices used to screen or diagnose patients. A Cameroonian team tackled this problem by developing a medical device (SON'OR © ) which integrates a new instrumentation amplifier structure dedicated to perform otoacoustic emissions (OAE) and brainstem evoked response audiometry (BERA). The major technical challenges to perform OAE and BERA are the synchronization and the amplification of signals of very low amplitude. In this work, we emphasize on the general criteria necessary and indispensable to achieve an optimal amplification. The application of a novel instrumentation amplifier structure characterized by its optimized noise factor in the case of BERA and OEA emissions provides simulations and experimental results fully in line with forecasts.

“…One approach to simplify the design www.intechopen.com and cut loops and feedbacks between the stages is to use as much orthogonality as possible [3]. This orthogonality is practiced in this chapter, between the circuit performances and the biasing of the nonlinear components, or simply between AC and DC circuit designs.…”

“…With full synthesis (in the remainder of this paper called, in short, synthesis), the methodology is meant in which both the 1902 K. VAN HARTINGSVELDT, C. VERHOEVEN AND A. VAN ROERMUND amplifier topology and circuit parameters are created from scratch in a systematic, non-iterative way, basically traversing a decision tree by means of explicit design rules and criteria that do not require complex analyses or calculations [1,2]. It directly leads the designer to the optimal topology and design solution, and as early as possible, in the synthesis process, it tells the designer if the given requirement specifications may be or certainly will not be feasible.…”

“…It has been used to support synthesis [2], but it lacks direct mapping to the circuit level, and in case of double-loop feedback amplifiers, it partially behaves as a black-box model, not indicating the presence of two feedback loops. Hence, it is not able to point towards the double-loop feedback-specific design criteria.…”

“…Secondly, it is extended to a double-loop synthesis model that enables the designer to synthesize double-loop feedback amplifiers in a hierarchical and systematic way, similar to their single-loop counterparts. With the help of this extended feedback model, the existing structured design methodology [2]-mainly focusing on the full synthesis of single-loop negative feedback amplifier-is complemented with additional design criteria for double-loop feedback amplifiers.…”

SUMMARYThis paper presents a new feedback model that focuses on the synthesis rather than the analysis of feedback amplifiers. First, a single-loop synthesis-oriented feedback model is developed that enables the full synthesis of such amplifiers in a hierarchical and systematic way. This model is subsequently extended to a double-loop synthesis model, so that also feedback amplifiers with a characteristic input or output impedance-employing two feedback loops-can be synthesized through the same systematic approach. That these new models are suitable for synthesis lies in the fact that they map directly to the circuit level, such that the intended, asymptotic behavior as well as the various individual contributors to the deviation from this intended behavior, like finite loop gain, non-ideal input and output impedances of the forward gain block, direct feed-through and attenuations outside the feedback loop(s), are clearly distinguished and can be assigned to the responsible sections of the network. For this purpose, the double-loop synthesis model makes the transfers of the two feedback networks explicitly visible, so that it gives immediate insight in how to design these networks to get the required signal transfer and characteristic impedance.
