Latest Patents
Among his latest innovations is an ECL integrated circuit that allows for fast operation. In this circuit, when the potential of an input signal A changes from 'L' to 'H', the output signal D correspondingly changes from 'H' to 'L'. At this moment, an output sent from a switching stage circuit is supplied to a gate of a PMOS transistor via a control capacitor. This design promotes the flow of base current in a pull-down transistor, facilitating a quicker change in the potential of the output terminal node. Additionally, an NMOS transistor is arranged between a node and the VEE supply terminal, which further enhances the output signal D's responsiveness.
Another notable patent is the Bi-CMOS output buffer circuit for CMOS-to-ECL conversion. In this design, the logic of an intermediate signal (Y.sub.1) goes high when an input signal (CI) transitions from 'L' to 'H'. This triggers a transistor (Q.sub.1) to turn on while another transistor (Q.sub.2) turns off. The NMOS transistor (N.sub.1) rapidly turns on when the input signal (CI) is at a CMOS level corresponding to logic 'H'. This configuration reduces the power consumption of the output buffer circuit while increasing the emitter potential of the output transistor (Q.sub.0).
