Are there any Analog FPGAs? - Electrical Engineering Stack Exchange
网页2012年1月23日 · One reason that analog FPGA's don't offer anywhere near the design flexibility of digital devices is that even if one passes a digital signal through dozens or hundreds of levels of routing and logic circuitry, each of which has a 10dB signal-to-noise ratio (SNR), meaning there's 1/3 as much noise as signal, the resulting signal can be clean.
adc - Interfacing Analog signal to FPGA? - Electrical Engineering …
网页2016年5月27日 · My main question is If I can interface an analog signal to a pin of the breadboard the BSB provides without having to use an external ADC. I want my FPGA to work with a binary digital signal translated from a analog one. In one of the documentation files, it is stated the signal name assigned to a pin …
What FPGA chips support verilog-ams or verilog-a
网页2011年12月29日 · Although modern FPGA's have these blocks in them, the analog parts are not re-configurable and the analog stuff is not exposed to the Verilog/VHDL programmer. Every couple of years some new FPGA maker pops up claiming to have "Analog FPGA's" or some similar buzzword. Most of the time it's the same FPGA as before, just bought by …
digital logic - Waveform generation on FPGA - Electrical …
网页2022年3月21日 · Can anyone give me an idea on how to generate this RF waveform on FPGA? I already have the I(cos) and Q(sin) signals generated just need a guide to produce this weird shaped pulse. Edit: This is the output waveform from FPGA. Now, only need to do the digital modulation to get the green graph SSB waveform as posted by @VVT
analog - Put a DAC at the output of FPGA - Electrical Engineering …
网页2014年5月12日 · I have designed a circuit by System Generator to implement on FPGA. The output signal is a sinusoidal with changeable frequency. I need to read the output signal by oscilloscope. I should put a DAC at the output since the output of FPGA is parallel and digital. I do not know how should I do this, since I am not familiar with DAC. My FPGA is ...
Choosing an FPGA based on ADC sampling rate
网页I believe this is a good application for a low-grade FPGA, so I am trying to understand how best to approach selecting a specific FPGA device. The math involved in the FPGA will be minimal. Basically, I need the 500 MHz sampling speed to capture the physical event, but the FPGA will be selectively discarding most of the samples.
What components can an FPGA replace/emulate?
网页2013年6月18日 · (However, there are many tricks people use to replace large amounts of analog circuitry and RF with a small amount of analog circuitry and a DSP, and the DSP itself can be replaced by a FPGA). Power circuits: voltage regulators, current limiters, over-voltage protection circuits, H bridges, maximum power-point trackers , power inductors, PoE ...
fpga - Analog video chrominance decoding - PAL/NTSC - Electrical ...
网页2020年8月18日 · I'm implementing an analog video decoder on FPGA. I find some difficulties during chrominance decoding. I appreciate if you can help me. These are the steps as I'm doing: I generate an NTSC ColorBar signal from a TV pattern Generator.
analog - Verilog data input - Electrical Engineering Stack Exchange
网页2014年11月21日 · It uses many pins (1 per bit) and as you increase the number of bits it becomes inaccurate quite quickly because of the differences of resistances in the resistors. Note that my charge integrator method is very similar to the R2R method; in the FPGA both have an up-running counter whose value is taken when an analog comparison occurs.
Possible to use FPGA to emulate TTL logic ICs in existing circuit?
网页2020年1月30日 · These have a large hysteresis that can't be provided in FPGA without external components. There are devices like 74xx06 with an high-voltage open-collector output, far beyond the capabilities of an FPGA. There are analog chips like 74xx624 that is an voltage controlled oscillator - that's outside the domain of what an FPGA can do.
