** PSoC® Creator™ Component Datasheet Programmable Gain Amplifier (PGA) Figure 2. PGA Schematic Vin Vout Vref Ra Rb The bandwidth of the PGA is determined by gain and power setting. Because of compensation capacitor and stability requirements, the bandwidth is somewhat...
A programmable gain amplifier (PGA) circuit includes a gain adjust circuit and a gain select circuit that are both coupled to an output of an amplifier. The gain select circuit comp
Provided is system for an improved programmable gain amplifier (PGA). The system includes an amplifier and a first gain control mechanism. The first gain control mechanism includes a circuit input por
This work describes the implementation of a 1.2-V programmable gain amplifier (PGA) for high-definition (HD) video digitizers in a 65-nm digital CMOS process. The "pseudo" switched-capacitor (SC) PGA architecture buffers the video signal, without switching, during the active video. The SC ci...
The output of the preamp is accessible, allowing for adjustment of gain using external resistors and for external filtering between the preamp and the PGA. programmable gain amplifier (PGA) The PGA is an inverting, programmable gain amplifier. The gain is digitally programmable using three control ...

The principle of operation is measuring bus and shunt voltages using a programmable-gain differential amplifier and an analog-to-digital converter. The schematic for one such circuit is shown in Figure 3. The two analog inputs are connected across a shunt resistor placed in series between the po...
Figure 2 shows a simplified schematic of an electrochemical sensor measurement circuit. Electrochemical sensors work by allowing gas to diffuse into the sensor through a membrane and by interacting with the working electrode (WE). The sensor reference electrode (RE) provides feedback to Amplifier U2...
A device may include a programmable gain amplifier and an analog-digital converter with pipeline architecture having several stages. The first stage of the analog-digital converter may incorporate the
This amplifier is used as the core of a programmable gain cell in the front-end part of a ÿÿ A/D converter. The good linearity performances are achieved thanks to a novel low impedance output stage which uses a simple but efficient...
