Analog Ground Plane Design in Cloning PCB Sensitive analog components such as amplifiers and voltage references are always referenced and decoupled to the Analog Ground Plane Design in Cloning PCB. The ADCs and DACs (and other mixed-signal ICs) with low digital currents should generally be treated as analog components and also grounded and decoupled to the analog…
Ground Plane Design in Circuit Board Reverse Engineering Ground planes also allow the transmission of high speed digital or analog signals using transmission line techniques (microstrip or stripline) where controlled impedances are required, as a result of that, Ground Plane Design must be taken into consideration of Circuit Board Reverse Engineering. The use of “buss wire”…
Soldering Integrated Circuit Ground Pin in PCB Reverse Engineering All soldering integrated circuit ground pin in PCB Reverse Engineering should be soldered directly to the low impedance ground plane to minimize series inductance and resistance. The use of traditional IC sockets is not recommended with high speed devices. The extra inductance and capacitance of even…
Shift Light Module Card Cloning Ground planes on Shift Light Module Card Cloning also allow the transmission of high speed digital or analog signals using transmission line techniques (microstrip or stripline) where controlled impedances are required. The use of “buss wire” is totally unacceptable as a ground because of its impedance at the equivalent frequency…
Fuel Cut Defencer PCB Board Reverse Engineeirng Related to the star ground system discussed earlier is the use of a ground plane on Fuel Cut Defencer PCB Board Reverse Engineeirng. To implement a ground plane, one side of a double-sided PCB (or one layer of a multilayer one) is made of continuous copper and used…
Separate AGND & DGND Through Reverse Engineering Circuit Board Note also that many ADCs and DACs have separate analog ground (AGND) and digital ground (DGND) pins through Reverse Engineering Circuit Board. On the device data sheets, users are often advised to connect these pins together at the package. This seems to conflict with the advice to connect…
Restore PCB Board to Separate Analog and Digital Grounds As a fact of life, digital circuitry is noisy. Saturating logic, such as TTL and CMOS, draws large, fast current spikes from its supply during switching. However, logic stages, with hundreds of millivolts (or more) of noise immunity, usually have little need for high levels of…
Mixed Signal PCB Reverse Engineering To further complicate the issue, Reverse Engineering Mixed Signal PCB can find that mixed-signal ICs have both analog and digital ports, and because of this, much confusion has resulted with respect to proper grounding techniques. In addition, some mixed-signal ICs have relatively low digital currents, while others have high digital…
Star Ground in PC Board Reverse Engineering The Star Ground in PC Board Reverse Engineering philosophy builds on the theory that there is one single ground point in a circuit to which all voltages are referred. This is known as the star ground point. It can be better understood by a visual analogy—the multiple conductors…
Signal Processing in Circuit Board Cloning Today’s signal processing in Circuit board cloning system generally require mixed-signal devices such as analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) as well as fast digital signal processors (DSPs). Requirements for processing analog signals having wide dynamic ranges increase the importance of high performance ADCs and DACs. …
