1. ΔV_BE thermometer outputs 1 mV/°C without calibration or op amps
   Stephen Woodward
   Circuits NXP 74HC4053
   Op amps tend to make analog design easy. Maybe sometimes too easy? Don’t get me wrong. I like operational amplifiers. Some of my best friends are op amps. They embrace such a wide range of varied capabilities, including low noise, high power, ...

2. BJT is accurate sensor for absolute temperature in Kelvin and Rankine
   Stephen Woodward
   Circuits NXP 74HC4053
   Simple math implemented in a (very) simple circuit. What’s not to like? A very cool (also warm!) property of the base-emitter junction of (most) small signal BJTs is the ΔV BE temperature-sensing effect. ΔV BE temperature ...
