摘要： A method and a system of credit risk control use different incentive mechanisms for different type of users for post-loan credit risk control. The method classifies the user to one of several different user types based on the user information and a correspondence relationship between the user information and risk levels, and selects an appropriate incentive mechanism for risk control based on the user type. The incentive mechanisms may either be a positive incentive mechanism or a negative incentive mechanism depending on the user type. The incentive mechanisms are performed over a network, and are designed to encourage a user of good loan payment record but to discourage a user of bad loan payment record. The method and the system are particularly suited for risk control of repayment of various kinds of loans which are applied and disbursed over the Internet.

摘要： A method and a system are disclosed for processing online joint guarantee. After a server receives an application from a user, the server provides various types of joint guarantee grouping to the user for selection. The server creates a joint guarantee group having a unique ID according to the selection of the user, organizes the information of the joint guarantee group into a data packet and sends the data packet to a bank system to be approved. The method potentially improves the success rate of joint guarantee grouping and removes the geographical limitations. Through the Internet, the method makes it possible to join companies of different geographical locations for online joint guarantee. The method also establishes a complete online alert mechanism, and realizes computerized loan risk control to improve the business credit system.

摘要： A mixed-signal integrated circuit (12) having compensation for leakage through an ESD cell (16) at an external terminal of a reference voltage is disclosed. A reference voltage generator circuit (14) generates a reference voltage that is low-pass filtered by an on-chip resistor (Rf) and an off-chip capacitor (Coc). The ESD cell (16) is connected at the terminal node between the resistor (Rf) and the capacitor (Coc), as is an ESD compensation circuit (20, 20′, 20″). The ESD compensation circuit (20, 20′, 20″) includes a dummy ESD cell (29) that is physically matched to the ESD cell (16), and a current mirror biased in a direction corresponding to the direction of the expected leakage through ESD cell (16). The ESD compensation circuit (20, 20′, 20″) ensures that very little of the leakage current through ESD cell (16) is conducted by the filter resistor (Rf), so that changes in this leakage current over temperature or bias conditions does not modulate the reference voltage.
