What are cross-coupled inverters?
The inverters are cross-coupled to form a flip-flop for storing data. The flip-flop is connected between a power source VCC and the ground. A single transfer gate MOS transistor Q0 is connected to the flip-flop for reading/writing data.
What is cross-coupled oscillator?
It is well known that input impedance of cross couple oscillator circuit has a fourth order denominator polynomial form in frequency domain. For example, it is the cascade of resonance amplifier one time which can be seen as a cross-coupled oscillator. It is composed of amplifier stage and feedback stage.
What is cross coupling in VLSI?
Crosstalk is a phenomenon, by which a logic transmitted in vlsi circuit or a net/wire creates undesired effect on the neighboring circuit or nets/wires, due to capacitive coupling.
What is cross coupling electronics?
Cross coupling can be considered to have inductive and capacitive components with waves traveling in both directions. We will refer to forward coupling when the coupled signal travels in the same direction as the driving or culprit wave.
How does an LC oscillator work?
LC Oscillators Summary In a simple inductor-capacitor, LC circuit, oscillations become damped over time due to component and circuit losses. Voltage amplification is required to overcome these circuit losses and provide positive gain. The overall gain of the amplifier must be greater than one, unity.
How does negative resistance help in oscillation?
. In general, a negative differential resistance is a two-terminal component which can amplify, converting DC power applied to its terminals to AC output power to amplify an AC signal applied to the same terminals. They are used in electronic oscillators and amplifiers, particularly at microwave frequencies.
What is SRAM cell?
A typical SRAM cell is made up of six MOSFETs. Each bit in an SRAM is stored on four transistors (M1, M2, M3, M4) that form two cross-coupled inverters. Two additional access transistors serve to control the access to a storage cell during read and write operations.
What is LC VCO?
Abstract – LC-tuned voltage controlled oscillators (LC VCOs) are widely used in high performance phase locked loops (PLLs) and frequency synthesizers due to their high spectral purity. The oscillation frequency of an LC VCO is commonly assumed to be the resonant frequency of the LC tank.
