a supply potential 46. The cathode of the first diode 34, the anode of the second diode 36, the cathode of the third diode 38, and the anode of the fourth diode 40 communicate with a ground potential 48.
The ESD protection circuit 30 optionally includes fifth and sixth diodes 50 and 52, respectively. An anode of the fifth diode 50 and a cathode of the sixth diode 52 communicate with the first terminal of the read element 32 and the first current source 42. A cathode of the fifth diode 50 and an anode of the sixth diode 52 communicate with a second terminal of the read element 32 and the second current source 44.
The current sources 50 and 52, respectively, bias the read element 32 during normalIn July my nephew Kailash was born in London. We headed over for a weekend to meet him when he was a month old.
That same weekend my cousin had a 50th birthday party, so it was a nice catchup with other relatives too, and on the same day in Malaysia my grandmother celebrated her 90th birthday!All the best people are born in July 😉

In August a friend got married in Crail (near St Andrews), so Lex and I headed down together for the evening ceilidh. It was a lovely film-themed wedding, and it was also a reunion of knitting group friends now in Glasgow, Edinburgh, Stirling, and Aberdeenshire.

Before leaving the next day, Lex and I had a wee wander round town in St Andrews.A scale model of The
