“…using a real operational amplifier, the voltage at the output of the circuit from Fig. 2 C is connected in parallel to the resistor F R when the circuit works in a wide frequency range mode to limit the high-frequency noise that can occur in the output [15], [16]. If the operational amplifier is considered an ideal active element for the pole frequency and the zero frequency of the reciprocal of the negative feedback coefficient (or Noise Gain -NG coefficient), the following expressions are obtained, respectively:…”

New photodetector structure combining thinned CdTe film with lead-free perovskite photoelectric film was produced and investigated. This setting of the CdTe thickness results in photodetector parameters’ competitiveness to the state-of-the-art in the field of advanced photoelectric materials. The device shows a promising sensitivity of ~40 μA/W, maximum responsivity of 10.6 mA/W at 460 nm, equal rise and fall times of 30 ms, and high linearity (maximum linearization error is less than 0.6 %). However, the optoelectronic performance of CdTe/lead-free perovskite structures integrated with signal processing circuit remains unexplored. For this purpose, Field Programmable Analogue Array (FPAA)-based mixed-signal processing circuit is developed for pulse width modulated electrical signal with duty cycle controlled by the illumination degree of the detecting photoelement. This novel approach guarantees a smooth change of the electrical output at a smooth change of the input illumination between the light and dark switching states and can be practically applied as a precise position detector of moving objects. The paper represents a synergistic connection between microelectronics, electronics, and signal technology.

“…Both the CCII+ and CFOA are useful to realize linear and nonlinear circuits Trejo-Guerra et al, 2010). Other useful mixed-mode active devices are the transimpedance amplifier (van der Horst et al, 2010), operational transresistance amplifier (OTRA) and current operational amplifier (COA) (Sánchez-López, . In the following section we show how to generate the fully-symbolic behavioral model of amplifiers and oscillators by including parasitic effects of the active devices.…”

“…The proposed solution is capable to operate at 1.8 V single supply voltage with a maximum power consumption of about 36.1 µW and allows to achieve variable gains up to about 124 dBΩ (with fine-and coarse-tuning capabilities) with a wide bandwidth up to about 1.15 MHz and low-noise characteristics, thus resulting as particularly suitable for integrated optoelectronic sensing systems in biomedical applications. Moreover, the complete theoretical analysis of the proposed circuit discussed in the paper opens the possibility to employ the same circuit architecture by a suitable sizing of the passive and active components, also for other kinds of input signals coming from wireless sources, such as RF antennas operating at wider bandwidths [31][32][33][34].…”

This paper reports on a novel solution for a transimpedance amplifier (TIA) specifically designed as an analog conditioning circuit for low-voltage, low-power, wearable, portable and implantable optoelectronic integrated sensor systems in biomedical applications. The growing use of sensors in all fields of industry, biomedicine, agriculture, environment analysis, workplace security and safety, needs the development of small sensors with a reduced number of electronic components to be easily integrated in the standard CMOS technology. Especially in biomedicine applications, reduced size sensor systems with small power consumption are of paramount importance to make them non-invasive, comfortable tools for patients to be continuously monitored even with personalized therapeutics and/or that can find autonomous level of life using prosthetics. The proposed new TIA architecture has been designed at transistor level in TSMC 0.18 μm standard CMOS technology with the aim to operate with nanoampere input pulsed currents that can be generated, for example, by Si photodiodes in optical sensor systems. The designed solution operates at 1.8 V single supply voltage with a maximum power consumption of about 36.1 μW and provides a high variable gain up to about 124 dBΩ (with fine- and coarse-tuning capabilities) showing wide bandwidth up to about 1.15 MHz and low-noise characteristics with a minimum noise floor level down to about 0.39 pA/Hz. The overall circuit is described in detail, and its main characteristics and performances have been analyzed by performing accurate post-layout simulations.
