Ansys HFSS normally uses the scattering parameters convergence as a termination condition. Although, this does not necessarily mean that the solution converged everywhere, it is a fast and efficient criterion. Few days ago, I was running the built in optimizer in HFSS searching for the...

Most microwave hardware is specified to run in a fifty ohm system. Why was this standard chosen? 50 ohms is a great compromise between power handling and low loss, for air-dielectric coax. The arithmetic mean between 30 ohms (best power handling) and 77 ohms (lowest loss) is 53.5, the...

As is well known, solderability is very important for the printed circuit boards, we must do solderability test of each batch PCB we made. In this way we can inspect the weldability of the PCB before we go ahead the assembly process, much helpful for SMT. Today we are going to discuss the...

PRACTICAL CONSIDERATIONS All this while, we’ve talked about the software side of things when dealing with the ADC. Now, it’s time to talk about the hardware side of things. We’ve considered many situations in the discussions above. But not all of them can be used in your circuits. One...

SEQUENTIAL STEPS IN ANALOGUE TO DIGITAL CONVERSION USING THE INTERNAL ADC So, here are the steps to configure the ADC and carry out the conversion: • Decide which pins need to be analogue, which pins need to be digital and which (if any) need to be configured as reference pins. • Select the...

ADC pinout of PIC 16F877A PIC16F877A has 8 ADC input channels. That means that 8 pins are multiplexed (connected) to the PIC ADC module. So, you can use the ADC module to convert analogue input from 8 inputs. PIC16F877A cannot do the conversions simultaneously, so it must be done one by...

Right/Left Justification continued When you have a 10-bit number (range is 0 to 1023), if you divide the number by 4, you effectively just converted the 10-bit number to an 8-bit number. The new range is 0 to 255. You should already know that bit-shifting a number to the right once is...

Acquisition Time Before an analogue to digital conversion is to be started, a small amount of time must be allowed for the holding capacitor of the PIC ADC module to fully charge to the input level. This is how the ADC works and unless this minimum time is allowed, the ADC will give an...

Introduction The ADC is used to convert an analogue input signal (an analogue voltage within a specific range) to a corresponding digital data that can be processed and used by the PIC. The PIC, without the conversion to digital, can do almost nothing with an analogue input (unless you use...

The maximum analog voltage you can give to your PIC (directly, without any divider) is 5V. So whatever analog signal you are trying to measure, make sure that the i/p volt to that pin should not exceed beyond 5V. If you want to measure voltage more than 5V, you should use resistor voltage...

There is a fact to mention about the resolution of the A/D converter. Since the converter converts the signals, it takes a certain time. The conversion time of the low resolution A/D takes less time than the conversion time of the high resolution A/D. You have to consider carefully : if you...
