Commonly used logic gates aretransistor-transistor logic(TTL) andcomplementary metal-oxide-silicon(CMOS). TTL ICs use negative-positive-negative and positive-negative-positive bipolar junction transistors. CMOS ICs are constructed from metal-oxide-semiconductor or junction-gatefield effect transistors. TTL ...
A Software Defined Radio (SDR) is a radio communication system that employs reconfigurable software-based components for processing and conversion of digital signals. Un
In the mid-1980s, with the ADVENT of CMOS DSP chip, its storage capacity and operation speed have been doubled, become the basis of voice processing, image hardware processing technology. In the late 1980s, the third generation of DSP chips came out. The computing speed is further improved...
CMOS Circuits Static Power Consumption gate circuits 2.5-5μW buffers and flip-flops 5 -20&μW medium-scale integrated circuits 25-100μW ●Input impedance The input impedance of the CMOScircuit onlylies on the leakage current of the protectiondiodeat the input end, soits value...
This PWM would not be enough to fully turn on a power device used in power systems, as its overdrive voltage generally exceeds the standard CMOS/TTL logic voltage. Thus, an interface is needed between the logic/control circuitry and the high power device. This can be implemented by drivi...

First had such thought, had such goal, turns the dream ideally into is the power, like this can change! Now we are the university student, we will be the future, will be the hope, will be later constructor, then my gate will only pursue the reality, will not pursue the dream, will...
The Inter-Integrated Circuit (I2C) bus is a two wire serial interface originally developed by the Phillips Corporation for use in consumer products. It is a bi-directional bus that is easily implemented in any IC process (NMOS, CMOS, bipolar) and allows for simple inter-IC communication. Conn...
Digital circuit design was first started up with a design ofrelays,later vacuum tubes,TTL Transistor-Transistor Logic, Emitter coupled logic, andCMOS logic.These designs use a large number of logical gates like AND, OR, NOT, etc integrated on a single IC. The input and output of digital dat...
CMOS levels– 0V and VDD like 3.3V or 5V ECL levels– -1.75V and -0.9V Using only two distinct levels minimizes errors and enables simple digital logic functions. Multi-level signaling is possible but is less common. Waveform Shapes
