摘要： An inductor equivalent circuit is disclosed. The circuit comprises a reference current source, a first current mirror, a second current mirror, two operational amplifiers OP1 and OP2, a capacitor, a first transistor, a second transistor, a mirror resistor set, and a bypass current source in parallel with the capacitor. An input signal is through OP1 and second transistor to control the reference current source. The first mirror current is then feed-back a signal to the first transistor through an OP2. The current signal makes the drain current of the first transistor lags the input voltage signal by 90° due to the capacitor coupled with the first mirror current source. The mirror resistor set can be resistors having one common terminal grounded, and other terminals each, respectively, coupled with the first and the second transistor and the capacitor, or can be composed of transistors and all of them with gate property biased so that the transistors in the mirror resistor set are operated in an ohmic region. The second mirror current provides an output current of the inductor equivalent circuit for next cascade stage.

摘要： A voltage clamping circuit that protects integrated circuits having multiple separate power supply voltage terminals from damage when an ESD event causes excessive differential voltages between the multiple separate power supply voltage terminals. The voltage clamping circuit has two subgroups of Darlington connected clamping transistors. The first subgroup of Darlington connected clamping transistors is connected between the first power supply voltage terminal and the second power supply voltage terminal. If the differential voltage exceeds the first clamping voltage level, the first subgroup of Darlington connected clamping transistors turn on and restore the first differential voltage to a level less than the first clamping voltage level. The second subgroup of Darlington connected clamping transistors connected between the second power supply terminal and the first power supply terminal. If the differential voltage exceeds the second clamping voltage level, the second subgroup of Darlington connected transistors turn on and restore the differential voltage to a level less than the second clamping voltage level.
