with these changes. His personal venture capital education also comes from the experience of the National Semiconductor period: because of its small scale, limited resources, and even insufficient products for all customers, someone must determine which customers have a bright future, which are worthy of long-term cooperation, and which customers need to be decisively rejected. The wallentan responsible for this decision must constantly make predicti

I. Chinese semiconductor device model naming method
The model of a semiconductor device consists of five parts (the models of the Field Effect Device, special semiconductor device, composite tube, pin tube, and laser device are only part 3, 4, and 5. The five parts have the following meanings:
Part 1: digital representation of the Number of valid electrodes for a
development of semiconductor technology, surface-mounted inductors, capacitors, and highly integrated power control chips
The cost is decreasing and the volume is getting smaller and smaller. This is not required because a low-Resistance Transistor can output a high power.
External High-Power FET. For example, for 3 V input voltage, the nfet on the chip can be used to obtain the output of 5 V/2a. Secondly,
Small and medium power applications can use
certain amount of space charge can generate a definite Built-in Electric Field to offset the diffusion. In the overhead layer approximation, space Charge is the charge provided by the ionic impurity center. Therefore, when the doping concentration is fixed, a certain amount of space charge corresponds to a certain barrier thickness. If the doping concentration is increased, the concentration of the ionic impurity center is increased, that is, the space charge density is increased. Therefore, wh

#. Phase distortion: The amplification circuit produces a phase shift to different frequency signals and also produces distortion.
#. Frequency Distortion | Linear distortion: Regardless of the spectral function or phase spectrum function changes, the corresponding time function waveform will be distorted, amplitude distortion and phase distortion is always called frequency distortion, they are caused by linear reactance element, so called linear distortion

In order to achieve a satisfactory pass rate, almost all products must first aging before leaving the factory. How can manufacturers improve their efficiency without reducing their aging time? This article introduces a new scheme for functional testing during the aging process to reduce and shorten the cost and time problems brought about by the aging process.In the semiconductor industry, the aging of devices has been controversial.

One-wire Demo on the stm32f4 Discovery BoardSome of the devs at work were struggling to get their software talking to a Dallas 1-wire device. I remember doing 1-wire comms back on the 1990s, but I hadn ' t do any 1-wire lately and all of my old code is for Proces Sors I no longer had running. But I had a weekend free, so I figured I ' d pulling some old 1-wire devices out of the junk bin and write a bit o ' code ...The 1-wire protocolThe Dallas (now Maxim
