SPICE it up: My favorite “proof-of-concept” simulations (Part 2)
In my last post, I explained what TINA-TI is and introduced how to use a transient simulation to check a circuit’s DC operating condition. Figure 1 shows the results of this simulation. Figure 1:...

JESD204B: How to calculate your deterministic latency
In my previous blog, I explained how to achieve deterministic latency by aligning the LMFC signals at the transmit (TX) and receive (RX) devices and using the release buffer delay (RBD) to set the data...

How to eliminate a power supply when using a fully differential amplifier
There’s a common misconception when designing with a fully differential amplifier (FDA). Designers often convert a single-ended bipolar signal into a differential signal with a DC offset to drive an...
