Mosfet Small Signal



MOSFET Small-Signal Amplifier Examples. We will illustrate the analysis of small-signal MOSFET amplifiers through two examples in this lecture. Example N29.1 (text example 4.10). Determine Av (neglecting the effects of RG), Rin, and Rout for the circuit below given that Vt=1.5V,KaW L=0.25 MA /V2, and VA=50 V The first step is to determine the DC operating. 250V to 600V Small Signal/Small Power MOSFET -20V to -250V small signal P-channel MOSFETs and 20 V to 600 V small signal N-channel MOSFETs for automotive, industrial, and consumer applications Infineon offers a wide range of small signal and small power MOSFETs.

2N7000BU / 2N7000TA
Features
• Improved Inductive Ruggedness
• Extended Safe Operating Area
Description
These N-channel enhancement mode field effect transis-
tors are produced using Fairchild's proprietary, high cell
density, DMOS technology. These products minimize on-
state resistance while providing rugged, reliable, and fast
switching performance. They can be used in most appli-
cations requiring up to 400 mA DC and can deliver pulsed
currents up to 2 A. These products are particularly suited
for low-voltage, low-current applications, such as small
servo motor control, power MOSFET gate drivers, and

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at TC = 25°C unless otherwise noted.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed
applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors
are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical
and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise.
Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global
problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
