Module optimizes analog circuit design

Pushing beyond the capability of standard CMOS (complementary metal-oxide semiconductor)-based analog circuit design, Jazz Semiconductor has made available a 17 GHz Vertical PNP (VPNP) module on its 0.18-micron RFCMOS platform. The new module advances analog circuit design especially for high voltage, complementary drive, or amplification requirements. VPNP module reportedly enables greater integration than currently available with existing CMOS, RFCMOS, and BiCMOS products.

Vertical PNP allows circuit designers to reduce their bill of materials, or die cost, by increasing the number of functions contained on a single die, says the company. When coupled with other features in Jazz 0.18-micron RFCMOS and SiGe BiCMOS platforms, the module allows for more integration of functions typically relegated to discrete devices scattered on a system board.

VPNP can be paired with either an advanced SiGe NPN transistor module (for a complementary SiGe BiCMOS process), or with an NFET device (N-type field-effect transistor) to achieve high-current complementary push-pull functions needed in circuit designs that require balanced performance, such as disk drive preamplifiers or laser drivers. Use of this complementary pair can also enable higher speeds over a wider operating range, a requirement for many analog circuits today.
