I have two examples of drivers of this type from recent work. The first is a cascaded 12AU7 driver. This design not only provides over 76v/v of mid band gain, but has an input capacitance of onlypf, and a high frequency -3dB point greater than 60kHz (dB at 20kHz). The second is a cascaded 6SN7 driver with unbypassed cathodes. In this Letter, a modulator driver design for a 50 Ω transmission Mach-Zehnder modulator has been achieved by exploiting an N-over-N cascode architecture at the output stage and an RCL termination network. Moreover, compared with previous work (shown in Table 2), this driver circuit has been implemented with relatively low power and low cost. Demonstration of the electrical and electro-optical performance shows that this driver is capable of enabling 20 Gbit/s optical interconnection with a. method for a CMOS differential cascode Class-E power amplifier with LC-tank based driver stage. The stabilization method is based on the identifica-tion of the poles and zeros of the closed-loop transfer function at a critical node. By adding a series resistor at the common-gate node of the cascode.

The cascode is a two-stage amplifier that consists of a common-emitter stage feeding into a would limit its usefulness to very low-impedance voltage drivers. uses a planar on-chip transformer as input-balun and for interstage matching. A high-current cascode stage is used for the driver and for the output stage. driver stage in the existing Bluetooth transceiver ICs. The outline of this paper is as follows. In Section II, the self- biased and bootstrapped cascode.
