Weba ADC implemented entirely in discrete components (2N3904, 2N3906, Resistors, Capacitors), without the use of MOS components anywhere in the modulator portion of the system. Ultimately, a ADC was built with a 1-bit sampling rate of approximately 500 Hz, with maximum func-tional bit-depth of 9-bits. The ADC was implemented in conjunction with Webuse a single-ended connection scheme to the ADC. It makes no sense to purchase a fully differential op amp, and then not use the differential output to interface to the differential input of the ADC. In most cases, the dual supply implementation is a trivial change from the single-supply implementation, so schematics may not be included.

Trade-offs Between CMOS, JFET, and Bipolar Input Stage …

WebOct 12, 2013 · BJT (bipolar junction transistor) are widely used an amplifier, oscillator, switch etc. It is a current-driven device ( MOSFET is voltage driven), the output current is equal to the input current times a factor which is called Gain. A basic BJT has three pins: the Base, Collector, and Emitter. WebMOSFETs are too noisy for many precision amplifier applications. If you have a low impedance source, for the lowest noise of any available monolithic amplifier, you need to go to a bipolar amplifier such as the LT1028 which has a white noise spectral density of 1.1nV/sqrt(Hz). (If that's not good enough, a discrete design can do better).

WebJul 6, 2014 · Saturation in transistors (BJTs) - why and how. When a bipolar junction transistor (BJT) is used to switch a load (e.g. a relay, an LED, a buzzer, a small motor, etc) ON and OFF, it is most often operated as a "saturated switch". This article explains saturation in BJTs - why it is used, and how to calculate the base resistor to ensure … Webdevice is the lowest. This can be seen in Figure 1, where the bipolar OPA2210 (with a quiescent current of 2.2 mA) has lower broadband noise (2.2 nV/rt-Hz) than either 3 nV/rt-Hz in the OPA2156 (CMOS) with an IQ of 4.4 mA, or 4 nV/rt-Hz in the OPA828 (JFET) with an IQ of 5.5 mA. This means that for high-

Flash ADCs have been implemented in many technologies, varying from silicon-based bipolar (BJT) and complementary metal–oxide FETs (CMOS) technologies to rarely used III-V technologies.
